- What is meant by the sample space of an experiment?arrow_forwardWhat is an experiment?arrow_forwardAn epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 360 people living in East Vancouver and finds that 42 have recently had the flu. The epidemiologist will recommend East Vancouver as a location for one of the vaccination programs if her sample data provide sufficient evidence to support the hypothesis that the true proportion of people who have recently had the flu is greater than 0.06. A test of hypothesis is conducted. What is the null hypothesis?A. The true proportion of residents who have recently had the flu is greater than 0.06.B. The sample proportion of residents who have recently had the flu is greater than 0.06.C. The true proportion of residents who have recently had the flu is 0.06.D. The sample proportion of residents who have recently had the flu is…arrow_forward
- According to Emergency Room Statistics, in any 6 month period, 15.2% of asthmatic children not on inhalers will have an asthmatic complication requiring the emergency room. A pharmaceutical firm has developed a new steroidal inhaler. The company believes that the use of this steroidal inhaler will decrease the percentage of asthmatic children requiring emergency room care for asthmatic complications. Because the FDA requires 2-sided hypothesis tests, the company tested the following claim: In any 6 month period, the percentage of asthmatic children using their steroidal inhaler that require emergency room care for asthmatic complications will not be 15.2%. To test their claim, they took a simple random sample of 260 asthmatic children and had them use a steroidal inhaler for 6 months. Of the 260 children, 60 required emergency room care for asthmatic complications at some time in the 6 month period. (c) What is the critical value which represents a boundary between the rejection region…arrow_forwardAccording to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.arrow_forwardAccording to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level. viii) Comparing p-value and α value, which is the correct decision to make for this hypothesis test? A. Reject H B. Fail to reject Ho C. Accept Ho D. Accept HA Enter letter corresponding to correct answer. (ix) Select the statement that most correctly interprets the result of this test: A. The result is statistically significant at .05 level of significance. Evidence supports the claim that the proportion of complaints due to identity theft in Alaska is less than 23%. B. The result is statistically significant at .05 level of significance. There is not…arrow_forward
- An automobile mileage study tested the following hypotheses. Hypothesis Conclusion H0: µ 25 mpg Manufacturer’s claim supported Ha: µ 25 mpg Manufacturer’s claim rejected; average mileage per gallon less than stated For σ 3 and a .02 level of significance, what sample size would be recommended if the researcher wants an 80% chance of detecting that µ is less than 25 miles per gallon when it is actually 24?arrow_forwardA real estate agent compares the selling prices of randomly selected homes in two municipalities in southwestern Pennsylvania to see if there is a difference. The results of the study are shown. Is there enough evidence to reject the claim that the average cost of a home in both locations is the same? Use the 0.01 level of significance.
