I NEED HELP 1. State whether each of the following would be a null hypothesis, an alternative hypothesis, or neither. If thestatement could be an alternative hypothesis, does the statement reflect a one-tail (directional) or two-tail(nondirectional) test?a) µz = 17b) µy z 115c) X = 2.93d) X ± 113e) µy > 8.75f) X < 99.22. The national norm for a junior high chemistry achievement test is a score of 90, with o = 18. The researchdirector of a school district wants to know whether the students in her district are substantially higher orlower than this national norm. She selects a random sample of 81 students who took this exam and finds amean of 93.a) State the null and alternative hypotheses.b) Using the z table, test the null hypothesis at the .05 level of significance and state your conclusions.c) Using the z table, determine the probability of obtaining a random sample from the national normsample (with a mean of 90) that would be as extreme or more extreme (either above or below thenational mean) than the obtained sample mean of 93. (Hint: This is really a Chap 11 type of problem).

The hypothesis is a statement about population parameters which we want to test. Note : Since you…

Suppose that you performed the following hypothesis test: H subscript O colon space p subscript 1 equals 0.4 semicolon space p subscript 2 equals 0.25 semicolon space p subscript 3 equals space 0.35H subscript A colon space NOT thin space H subscript O and that you got a Test Statistic (TS) that. yielded a PValue (PV) = 0.045. If you ran this hypothesis test with a value of alpha = 0.05, which of the following choices gives the correct Decision and Conclusion? A. Since the PV is less than alpha, I Fail to Reject the Null hypothesis and conclude that at least two of the population proportions are significantly different from their null-hypothesized values. B. Since the PV is less than alpha, I Reject the Null hypothesis and conclude that the population proportions are NOT significantly different from their null-hypothesized values. C. Since the PV is less than alpha, I Reject the Null hypothesis and conclude that at least two of the population proportions are significantly different…
