Anna suspected that when people exercise longer, their body
temperatures change. She randomly assigned people to exercise for
30 or 60 minutes, then measured their temperatures. The 18 people
who exercised for 30 minutes had a mean temperature of 38.3º C with
a standard deviation of 0.27º C. The 24 people who exercised 60
minutes had a mean temperature of 38.9º C with a standard deviation
of 0.29º C.
Assume Anna will use the conservative degrees of freedom from

15 highly anxious students were randomly assigned so that 5
received behavioral therapy, 5 received cognitive therapy, and 5
received psychoanalytic therapy. Later all 15 students were tested
for anxiety (on a scale where the higher the score the greater the
anxiety). The results of these measures appears below. On the basis
of these data determine whether the therapies differ in their
effectiveness.

SOLVE USING R. COPY AND PASTE R INPUT AND OUTPUT.
Fifteen turkey hens were randomly assigned to three groups of
five. One group was given diet A, the second group diet B, and the
third group diet C. We wish to know if there is a difference in the
weight of eggs produced by the birds on these diets, and if so,
which diet results in the largest eggs. The data are the mean
weights of ten eggs from each...

pain reliever that cost $2.50 each. The second group received the
same placebo pills, but was told the pills were $.10 each. Each
group received a mild electrical shock before and after taking the
pills. They were then asked if the pills reduced the pain. In the
