Determine whether to reject H0. Use the =α0.05 level of significance.▼(Choose one) H0 at the =α0.05 level.

The rejection region for testing the hypothesesH0: μ = 100HA: μ ≠100at the 0.05 level of significance is:Group of answer choices|Z| > 1.96.Z < 2.33.|Z < 0.95.Z > 1.65.

If a hypothesis is rejected at the 0.025 level of significance, it:Group of answer choicesmust be rejected at any level.must not be rejected at the 0.01 level.must be rejected at the 0.01 level.may be rejected or not rejected at the 0.01 level.

Suppose we are conducting a hypothesis test with the following hypotheses:H0: p = 0.7H1: p > 0.7Furthermore suppose we get a p-value of 0.07 while using = 0.05, which of the following is the correct decision?a.At the 5% level of significance, there is significant evidence to reject H1 and retain H0.  b.At the 5% level of significance, there is significant evidence to retain H0c.At the 5% level of significance, there is significant evidence to reject H0 in favour of H1.  d.At the 5% level of significance, there is not significant evidence to reject H0.

(iv) Make a decision and conclusion for the hypothesis test in context. Use a significance level of 5% (α = 0.05).

Suppose that some hypothesis H_0 was rejected at the α1 = 0.05 level of significance. If the same hypothesis test is repeated with the same evidence but at the new significance level of α2 = 0.01 then which of the following are true? Select one or more answers.Group of answer choicesH_0 may be retained.The p-value of the second test will be higher.H_0 will be rejected.The p-value of the second test will be lower.H_0 will be retained.
