A random sample of 36 subjects who identified themselves as compulsive buyers was obtained and given a questionnaire. They had a mean questionnaire score of 0.59 with a standard deviation of 0.12. Test the claim that the population of self-identified compulsive buyers has a mean greater than the mean of 0.56for the general population. Use a 0.05 significance level.

Expert Solution

Ho:The population of self-identified compulsive buyers has a mean equal to the mean of 0.56 for the general population.
Ha:The population of self-identified compulsive buyers has a mean greater than the mean of 0.56 for the general population.

Thus we can conclude that the population of self-identified compulsive buyers has a mean not greater than the mean of 0.56 for the general population.

A random sample of 20 subjects was asked to perform a given task. The time in seconds it took each of them to complete the task is recorded below: 49, 26, 46, 40, 37, 39, 33, 47, 31, 35, 39, 43, 28, 38, 41, 29, 38, 34, 45, 41 If we assume that the completion times are normally distributed, find a 95% confidence interval for the true mean completion time for this task. Then complete the table below. Carry your...

6. Researchers obtained a sample of 36 college students who all have the same history instructor this semester. Half of the students were shown a 2-min video that claimed the purpose of education was to help students “learn how to learn” so that they can enjoy a lifetime of learning after college. The other half of students were shown a 2-min video that claimed the purpose of education was to teach facts to students. After watching the 2-min videos, the...

A random sample of subjects who tested positive for influenza during the 2014-15 flu season was obtained. There are four different influenza type: A/H1N1, A/H3N3, A-unsub, and B. Each subject was classified by age group and influenza type. Determine whether there is evidence at the 5% significance level that age group and influenza type are associated. Fully justify! Include hypotheses, test used, test statistic, p-value, decision and conclusion. You should put the frequencies into a matrix. Also report the Observed...
