for 7d, show working, formula and numbers inputted to the formula

annual trip frequencies to the nearest state park: where the subscript '1' denotes the white population and the subscript '2' denotes the 7. A survey of the white and nonwhite population in a local area reveals the following = 4.1, = 3.1, s = 14.3, s= 12.0, %3D n, = 20 ng = 16 nonwhite population. , Assume that the variances are equal, and test the null hypothesis that there is no difference between the park-going frequencies of whites and nonwhites. b. Repeat the exercise, assuming that the variances are unequal. G. Find the p-value associated with the tests in parts (a) and (b). d. Associated with the test in part (a), find a 95% confidence interval for the difference in means. e. Repeat parts (a)–(d), assuming sample sizes of n, = 24 and n, = 12. Tost the bunothes
