Compute a one-sample t-test comparing the age of your invented sample to the age of the general population of college students in traditional on-ground universities. Assume the population mean is 21. Any other required data may be fabricated. Please include a paragraph of interpretation of the results.© BrainMass Inc. brainmass.com October 17, 2018, 11:40 am ad1c9bdddf
This solution is comprised of a detailed explanation of one-sample t-test. This solution mainly discussed the question in which we defined null and alternative hypothesis, calculating the test statistics and p-value and provided the decision about the null hypothesis. Full interpretation are provided for the output and Minitab software is used to do the calculations.

Thirteen randomly selected volunteer A,B,...,M are administered a pill designed to lower systolic blood pressure with the following results.
Volunteer A B C D E F G H I J K L M
Before 115 135 140 130 135 150 122 135 138 190 180 99 110
After 120 128 142 112 111 150 110 135 126 180 160 103 108
Is there evidence to suggest that the pill is not effective?
If a significance level of α=.15 is given, find the critical region of your test.
A certain university's brochure claims that the average amount of money needed for boarding and lodging in the town for a single student is $75 per week. A random sample of nine single students from this university showed the following weekly expenditures:
75, 92, 80, 84, 73, 60, 84, 91, 78
Is there evidence to suggest that the university's estimate is not correct? Assuming that the weekly expenditures are normally distributed, also apply the t-test to analyze the same data.View Full Posting Details
