I need help solving all questions.

For the following hypothesis: H0: m S 70 HA' m > 70 with n = 210,i=712, s = 6.9, and a = 0105, state a. the decision rule in terms of the critical value of the test statistic b. the calculated value of the test statistic c. the conclusion Q8 For the following hypothesis test: H0: m = 60.5 HA: m at 60.5 a = 0.5 with n =15, s = 7.5, andi= 62.2, state a. the decision rule in terms of the critical value of the test statistic b. the calculated value of the test statistic c. the conclusion 0.9 For the following hypothesis test: Ho: =16 H.: 01:16 01:0.01 with n=10H :1 =20.6, state a. the decision rule in terms of the critical value of the test statistic b. the calculated value of the test statistic c. the conclusion Given the following null and alternative hypotheses H0102 = 100 HA: 0-2 9E [00 a. Test when n = 27. s = 9, and a = 0.10. Be certain to state the decision rule. b. Test when n = 17, s = 6, and a = 005. Be certain to state the decision rule. Q11 The following data for the dependent variable, y, and the independent variable, 1, have been collected using simple random sampling 1:. Compute the correlation coefcient b. Conduct a test of hypothesis to determine if there exists a correlation between the two variables in the population.
