how do you do

iologist claims that the mean length of mature female pink seaperch is different in fall and winter. Asample of 17 mature female pink seaperch collected in fall has a mean length of 117 millimeters and a standard deviation of 14 millimeters. Asample of 8 mature female pink seaperch collected in winter has a mean length of 107 millimeters and a standard deviation of 11 millimeters. At =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. (a) Identify the claim and state H, and H_ Which is the correct claim below? O A. "The mean length of mature female pink seaperch is different in fall and winter." O B. "The mean length of mature female pink seaperch is greater in the winter than in the fall." O C. "The mean length of mature female pink seaperch is greater in the fall than in the winter." O D. "The mean length of mature female pink seaperch is the same in fall and winter." What are Ho and H_? The null hypothesis, Hy, is The alternative hypothesis, Hy, is Which hypothesis is the claim? The null hypothesis, Ho O The alternative hypothesis, H_ (b) Find the critical value(s) and identify the rejection region(s). Enter the critical value(s) below. (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) Select the correct rejection region(s) below. OA. - to to OD. tto (o) Find the standardized test statistic. t= (Type an integer or decimal rounded to three decimal places as needed.) 'd) Decide whether to reject or fail to reject the null hypothesis
