please help

37. Suppose you repeated your hypothesis test over and over again with many different data sets. Which of the following statements is true? Group of answer choices The significance levels would change but the p-values would stay the same. The significance level would stay the same and so would the p-values. The significance level would stay the same but the p-values would change. The significance levels would change and so would the p-values.    (THANK U)

If the null hypothesis is false, you cannot make which kind of error? Type I Type II

State if you would retain or reject the null hypothesis 7. p>.05 8. p<.05 9. critical value = + and -1.96, test statistic = -1.98 10. critical value = + 1.65, test statistic = -1.90

Help with nr 11

4. Explain the procedure for testing a hypothesis using the P-value approach? What is the criterion for judging whether to reject the null hypothesis?

Help please

I understand how the level of signficance = 1.96 and I understand: Ho:μ=5    -   Ha:μ<5 But I need help understanding how to calculate the test statistic. I know we have a sum of 93 with a sample size of 28 but how do you come to the conclusion for the test stastisic and how do you figure out whether you have enough proof to accept or reject the claim? Thank you.
