Question 1132974: ) Here we consider the sleep habits of med students versus non-med students. The study consists of the hours of sleep per day obtained from 24 med students and 32 non-med students. The summarized data is given in the table. Here, x¯ is the mean hours of sleep per day from each sample. The degrees of freedom (d.f.) that you must use in your calculations are given below.
Student Type n x¯ s2 s
Med (x1) 24 5.9 0.7921 0.89
Non-Med (x2) 32 6.5 1.8225 1.35
degrees of freedom: d.f. = 53
Test the claim that the mean hours of sleep for med and non-med students is different. Use a 0.05 significance level.
(a) Find the test statistic.
You can put this solution on YOUR website! The test statistic is a t with df=54 (n1+n2-2)
critical value is |t|>2.01
calculated t value is -2 which gives a p-value of 0.0506
