A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovensis greater than the repair cost for type IlI ovens. A sample of 35 type I ovens has a mean repair cost of $80.39. The population standarddeviation for the repair of type I ovens is known to be $24.63. A sample of 31 type I|| ovens has a mean repair cost of $73.47. Thepopulation standard deviation for the repair of type |l ovens is known to be $10.42. Conduct a hypothesis test of the technician's claim atthe 0.05 level of significance. Let u be the true mean repair cost for type I ovens and u2 be the true mean repair cost for type Il ovens.Step 2 of 5: Compute the value of the test statistic. Round your answer to two decimal places.

CarMD reports that the cost of repairing a hybrid vehicle is falling even while typical repairs on conventional vehicles are get-ting more expensive. The most common hybrid repair, replacing the hybrid inverter assembly, had a mean repair cost of $ 3,927 in 2012. Industry experts suspect that the cost will continue to de-crease given the increase in the number of technicians who have gained expertise on fixing gas– electric engines in recent months. Suppose a sample of 100 hybrid inverter assembly repairs completed in the last month was selected. The sample mean repair cost was $ 3,800 with the sample standard deviation of $ 500. Is there evidence that the population mean cost is less than $ 3,927? (Use a 0.05 level of significance.) Determine the p- value and interpret its meaning.
Tardigrades, or water bears, are a type of micro-animal famous for their resilience. In examining the effects of radiation on organisms, an expert claimed that the amount of gamma radiation needed to sterilize a colony of tardigrades no longer has a mean of 900 Gy (grays). (For comparison, humans cannot withstand more than 10 Gy .) A study was conducted on a sample of 27 randomly selected tardigrade colonies, finding that the amount of gamma radiation needed to sterilize a colony had a sample mean of 907 Gy , with a sample standard deviation of 17 Gy . Assume that the population of amounts of gamma radiation needed to sterilize a colony of tardigrades is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that μ , the mean amount of gamma radiation needed to sterilize a colony of tardigrades, is not equal to 900…

Many smartphones, especially those of the LTE-enabled persuasion, have earned a bad rap for exceptionally bad battery life. Battery life between charges for the Motorola Droid Razr Max averages 20 hours when the primary use is talk time and 7 hours when the Internet applications (The wall Street Journal, March 7, 2012). Since the mean hours for talk time usage is greater than the mean hours for Internet usage, the question was raised as to whether the variance in hours of usage is also greater when the primary use Sample data showing battery hours of use for the two applications follows:Primary use talking:35.8 22.2 4.0 32.6 3.5 42.58.0 3.8 30.0 12.8 10.3 35.5Primary use Internet:24.0 12.5 36.4 1.9 9.95.4 1.0 15.2 4.0 4.7a. Formulate hypotheses about the two population variances that can be used to determine if the population variance in battery hours of use is greater for the talk time application. b. What are the standard deviations of battery hours of use for the two samples? c.…
When you get a surprisingly low price on a product do you assume that you got a really good deal or that you bought a low-quality product? Research indicates that you are more likely to associate low price and low quality if someone else makes the purchase rather than yourself. In a similar study, 16 participants were asked to rate the quality of low-priced items under two scenarios: purchased by a friend or purchased yourself. The results produced a mean difference of 2.6 and a SS = 135, with self-purchases rated higher. Is there evidence that the judged quality of objects significantly increase for self-purchases than for purchases made by others? Please use a one-tailed test with level of significance of 5%.
A regional retail corporate team is contemplating a decision to purchase an automated customer service system. The mean cost of a phone call handled by an automated menu customer service system is $0.75 while the mean cost of a phone call passed onto a “live” operator is $7.00. However, empirical data show that as more and more companies have implemented automated systems, customer annoyance with such systems has grown substantially. Many customers are quick to leave the automated system when given an option. According to the Center for Marketing Research, 40% of all callers to automated customer service systems automatically opt to go to a live operator when given a chance.What if the company decided to base their decision on the results of the analysis on the following information: If ten independent callers contact an automated customer service system, what is the probability that: a. None will automatically opt to talk to a live operator? b. Exactly 1 will automatically opt to talk…

Tardigrades, or water bears, are a type of micro-animal famous for their resilience. In examining the effects of radiation on organisms, an expert claimed that the amount of gamma radiation needed to sterilize a colony of tardigrades no longer has a mean of 1350 Gy (grays). (For comparison, humans cannot withstand more than 10 Gy .) A study was conducted on a sample of 18 randomly selected tardigrade colonies, finding that the amount of gamma radiation needed to sterilize a colony had a sample mean of 1375 Gy , with a sample standard deviation of 75 Gy . Assume that the population of amounts of gamma radiation needed to sterilize a colony of tardigrades is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that μ , the mean amount of gamma radiation needed to sterilize a colony of tardigrades, is not equal to 1350 Gy .
An American medical team wishes to test whether passive smoking affects the chance of children contracting bronchitis. Historically, the disease has been known to occur at least once in 20% of children aged 12. The team analysed the results of a random sample of 250 12-year-old children who were passive smokers, and found that 30 of these had contracted bronchitis at least once in their lives. Use a 5% level of significance to test the claim that the proportion of children who are passive smokers is 20%. What is the null and alternate hypotheses What is the value of the test statistic from below z = 3.16 z = -3.16 z =3.89 z = -3.89 What is the p-value from below 0.0016 0.0008 0.0000 0.0001 Based on this evidence, what is the conclusion
A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in New York and Illinois. Due to recent trends in the childcare industry, the firm suspects that the that the mean annual income of childcare workers in the state of New York is greater than the mean annual income of childcare workers in Illinois. To see if this is true, the firm selected a random sample of 20 childcare workers from New York and an independent random sample of 20 childcare workers from Illinois and asked them to report their mean annual income. The data obtained were as follows. Annual income in dollars New York 46686 , 34979 , 47325 , 48892 , 51128 , 56792 , 47785 , 48995 , 57301 , 55176 , 48002 , 45718 , 50351 , 58527 , 47067 , 53699 , 54361 , 49727 , 36426 , 50870 Illinois 48009 , 46871 , 42774 , 49790 , 43163 , 45401 , 41068 , 50300 , 47064 , 42003 , 47775 , 41917…
Each year, marketing and information firm J.D. Power and Associates surveys new car owners 90 days after they have purchased their cars. The data collected are used to rate auto brands (Toyota, Ford, and others) on initial quality and initial customer satisfaction. USA Today reported both the number of manufacturing defects per 100 vehicles and a satisfaction score for all 33 brands sold in the United States.† A research group decides to compare the mean number of defects for 2 specific models of cars, A and B, made this year by taking random samples of 100 cars of each model. (a) After collecting the data, the research group calculates a 95% confidence interval to estimate the difference in population means. In this case, what is the population? all cars for models A and B that were produced this yearthe defects all cars made this yearthe 100 cars from each model (b) Suppose the calculated confidence interval is (84, 92) number of defects.
