A marıne biologist claims that the mean length of mature female pink seaperch is different in fall and winter. A sample of 17 mature female pink seaperch collected in
fall has a mean length of 111 millimeters and a standard deviation of 10 millimeters. A sample of 8 mature female pink seaperch collected in winter has a mean length
of 98 millimeters and a standard deviation of 12 millimeters. At a = 0.10, can you support the marine biologist's claim? Assume the population variances are equal.
Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e) below.
OC. "The mean length of mature female pink seaperch is the same in fall and winter."
D. "The mean length of mature female pink seaperch is different in fall and winter."

Which hypothesis is the claim?
The alternative hypothesis, Ha
O The null hypothesis, Ho
(b) Find the critical value(s) and identify the rejection region(s).
Enter the critical value(s) below.
