All together ! With question In 2015, the mean number of books that college students wouldbuy was 35. With the use of Open Educational Resources, it isbelieved that this number has been decreasing. A recent sampleof so college students found a sample mean of 34 books and asample standard deviation of 5.1 books. We will perfrom ahypothesis test to determine if this is strong evidence that themean number of books that college students purchase isdecreasing and the use of Open Educational Resources isincreasing.Define your variable.O Let u be the mean number of books that college students inthe sample buy.Let p be the proportion of students that buy books.O Let u be the mean number of books that college studentsbuy.Let p be the proprotion of college students in the samplethat buy books.Write your hypotheses:Ho: ? 0?

The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1750pounds and a standard deviation of 50 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, μ, of the cables is now greater than 1750 pounds. To see if this is the case, 90 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1756 pounds. Can we support, at the 0.05 level of significance, the claim that the population mean breaking strength of the newly-manufactured cables is greater than 1750 pounds? Assume that the population standard deviation has not changed.Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. A. Find the value of the test statistic and round to 3 or more decimal places.

The National average GRE scores of graduate students in the US is known to be 500 (μ) with standard deviation (σ)of 100. The University of Smart Kids in Indiana boasts that their incoming graduate students have higher aptitude (asmeasured by GRE) than the national average. To substantiate the claim, the university randomly selects the GREscores of 1000 (n) incoming students and finds the average for the sample to be 575 (#$). Does the data provideenough evidence to support that claim?
CNN/Money reports that the mean cost of a speeding ticket, including court fees, was $150.00 in 2002. Alocal police department claims that this amount has increased. To test their claim, they collect data from asimple random sample of 160 drivers who have been fined for speeding in the last year, and find that theypaid a mean of $154.00 per ticket. Assuming that the population standard deviation is $17.54, is theresufficient evidence to support the police department’s claim at the ? = 0.01 significance level?
A campus located in Jakarta wanted to find out if students' independent study hours during the pandemic had increased. It is known that before the pandemic, the average student study hours were 15 hours/week with a standard deviation of 3 hours/week. To answer the questions above, the campus conducted a survey of 150 students. The survey results show that on average, students study independently for 18 hours/week with a standard deviation of 2 hours/week. Based on the information above, determine: Null and alternative hypotheses to test the statement that there is an increase in learning hours during a pandemic Based on the results of the survey, with a 95% confidence level, what conclusions can you convey to the campus leadership? If the standard deviation of study time before the pandemic is unknown, with a 95% confidence level, what conclusions can you convey to the campus leadership? Based on your answer to no. 2 above, if you want to get 90% confidence, based on the survey…
A tea shop has relocated to a new area and wants to make sure that all tea cups are consistent in tea whitener quantity to maintain the quality. Tea shop owner believes that each tea cup has an average of 4 oz. of whitener. If this is not the case, they must increase the amount to make a quality ‘milk leaf tea’ type of tea. For this purpose, he took a random sample of 25 tea cups, which showed a mean of 4.6 oz. of tea whitener and a standard deviation of 0.8 oz. Can the tea shop owner have 90 % confidence that the mean value of the tea whitener is not above 4 oz? Assume that distribution of alternate hypothesis is centralized at mean equal to 4.6 oz. Now using same standard error of mean as in part (a), graph the null and alternate hypotheses distributions by shading Type 1 and Type 2 error regions on them, taking =0.01. NOTE: DO NOT SOLVE ON EXCEL CLASSIFY EACH STEP
During a recent year, the mean ACT score for all college bound students had a mean of 24.65 and a standard deviation of 4.01. The director of Stanley Kaplan is interested in knowing whether taking their course causes a difference on ACT scores. She takes a random sample of 444 seniors and finds their mean to be 25.44. Test the null hypothesis at the .05 level of significance.
The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1950 pounds and a standard deviation of 50 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, μ , of the cables is now greater than 1950 pounds. To see if this is the case, 90 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1964 pounds. Can we support, at the 0.10 level of significance, the claim that the population mean breaking strength of the newly-manufactured cables is greater than 1950 pounds? Assume that the population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1800 pounds and a standard deviation of 95 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, μ, of the cables is now greater than 1800 pounds. To see if this is the case, 70 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1829 pounds. Can we support, at the 0.10 level of significance, the claim that the population mean breaking strength of the newly-manufactured cables is greater than 1800 pounds? Assume that the population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. a. State the null hypothesis H0 and the alternative hypothesis H1. b.
