In doing a hypothesis test of the population proportion at α=0.02 level of significance, we got the p-value to be 0.006. What would our conclusion to the test be? Why? A. Do NOT Reject H0 since the p-value > α B. Reject H1 since the p-value < α C. Reject H0 since the p-value < α D. Do NOT Reject H0 since the p-value < α
Suppose we want to test the null hypothesis H0 : p1 − p2 = 0.2 against the alternative hypothesis Ha : p1 − p2 < 0.2 at the 5% level of significance. Suppose also that x1 = 80, n1 = 100, x2 = 40, n2 = 80. What is the observed test statistic for this test?
If Ho: µ = 50 and the computed value of the test statistic Z = (x - μ0)/(σ/√n) is 1.75, compute for the p-value when: Ha: µ > 50. Should Ho be rejected at 0.05 level of significance? Ha: µ < 50. Should Ho be rejected at 0.05 level of significance? Ha: µ ≠ 50. Should Ho be rejected at 0.05 level of significance?
Which of the following statements is true if when using null hypothesis testing, our p value (in the "sig" column of SPSS output) is 0.069? a) Reject the null hypothesis b) Fail to reject the null hypothesis c) Reject the alternative hypothesis d) Fail to reject the alternative hypothesis

Q15- Consider the following null hypothesis: Ho: μ=30 Given a sample of n=16 and with x̅ =29.4, s=0.5 and α=0.04 - What is the alternative hypothesis H1 - What kind of test you are going to use? - t x̅ = - tα/2 = -What is your test conclusion? and why?
Which of the following statements is true if when using null hypothesis testing, our p value (in the "sig" column of SPSS output) is 0.051? Reject the null hypothesis Fail to reject the null hypothesis Reject the alternative hypothesis Fail to reject the alternative hypothesis
The test statistic of z=2.42 is obtained when testing the claim that p>0.1. a- identify the hypothesis test as being two-tailed, left-tailed or right tailed b- Find the P value c- Using a significance level of a=0.05, should we reject Ho or should we fail to reject Ho?
Choose among the following: A. the prevalence of hypertension among the three towns are equal B. there has been a change in the prevalence of hypertension in the town of San luis C. the prevalence of hypertension in San Luis is equal to the prevalence in Galindo D. Ho = 0.15 Should the null hypothesis be focused on San Luis, since that was required of us? Thanks!
The P-value for a hypothesis test is 0.06. For each of the fol-lowing significance levels, decide whether the null hypothesis should be rejected. a. α = 0.05b. α = 0.10 c. α = 0.06
The test statistic of z=2.26 is obtained when testing the claim that p≠0.659. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of α=0.01, should we reject H0 or should we fail to reject H0?
A test of Ho: p = 0.5 versus Ha: p > 0.5 has a test statistic of z = 2.19. What is the P-value for the test? If the alternative hypothesis were Ha: p ≠≠0.5, what would be the value of the P-value?
