Dental Anxiety Study: Study of adults who completed the Dental Anxiety Scale scored from 0
(no anxiety) to 25 (extreme anxiety). The Summary statistics for the scores of 20 adults who
completed the questionnaire are x̅= 11.9 and s = 3.8
Conduct a test of Hypothesis to determine whether the mean anxiety scale score for the
population of College students differs from μ = 14. Use p-value

Expert Solution

t test hypothesis calculation.

Here level of significance (α) not given so, by default we assume it as 0.05. We assume the same when alpha not given .

a study of student’s attitudes towards college varies on a scale from 0 to 180 and has a mean µ = 118 and a standard deviation σ = 19. The null and alternative hypotheses I wish to test are: H_o: μ=118 against H_a: μ>118 One sample of 24 students had a sample mean of x-bar = 124.7. Find the exact p-value associated with this sample (hint: you'll need to use the normal distribution table). A .0418 B .9140 C .9582 D 1.65...

The National Heart, Lung, and Blood Institute completed a large-scale study of cholesterol and heart disease, and reported that the national average for blood cholesterol level of 50-year old males was 210 mg/dl. A total of 89 men with cholesterol readings in the average range (200 – 220) volunteered for a low cholesterol diet for 12 weeks. At the end of the dieting period their average cholesterol reading was 204 mg/dl with a SD of 33 mg/dl. a. What is...
