A marine 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 117 millimeters and a standard deviation of 14 millimeters. A sample of $ 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 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, Ho. 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. 0 (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. O A. - to to (o) Find the standardized test statistic. 1= (Type an integer or decimal rounded to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. the null hypothesis. (e) Interpret the decision in the context of the original claim. At the 10 % significance level, enough evidence to support the claim that the mean lengths of mature female pink seaperch are different in fall and winter
