There is ▼ sufficient not sufficient evidence to conclude that the mean of the population of pulse rates for adult females is ▼ not less than greater than 70 bpm.Kevin, a Human Resources professional, would like to make the claim that the average hourly wage for administrative workers at his company is less than $9.69. Kevin samples 15 workers and obtains a sample mean of $8.80 per hour. At the 1% significance level, should Kevin reject or fail to reject the null hypothesis given the sample data below?
- Below are the numbers of years that archbishops and monarchs and a certain country lived after their election or coronation. Treat the values a simple random sample is from larger populations. Use a 0.05 significance level to test the claim that the mean longevity for archbishops is less than the mean for monarchs after coronation. A. Use a 0.05 significance level, and test the claim that the mean longevity for archbishops is less than the main for monarchs after coronation. What are the Null and alternative hypotheses? Assuming that population one consists of the longevity of archbishops and population two consists of the longevity ofMonarchs. The test statistic is?The drug Ritalin is designed to stimulate the central nervous system. In a random sample of 252 boys aged ten – twelve years old, it was found that 44 of the boys were taking Ritalin. It is known that the proportion of all boys aged 13 – 15 who take Ritalin is 24%. A researcher claims that the population proportions of boys who take Ritalin aged 10 – 12 is different than boys aged 13 – 15. Can you support this claim at the 5% significance level? a. Conduct a hypothesis test to test the claim at the 5% significance level. Be sure to state you Ho and Ha, your test statistic and p-value, whether or not you reject Ho and whether you support the claim. b. Show that you can use the large sample methodology. c.
