To test H0: mean = 80 vs. H1: mean < 80, a simple random sample of size n = 22 is obtained from a population that is known to be normally distributed. (a) If x-hat = 76.9 and s = 8.5 compute the test statistic (b) If the researcher decides to test the hypothesis at the a = 0.02 level of significance, determine the critical value. (c) Draw a t-distribution that depicts the critical region (d) Will the researcher reject...

Find the critical value for the indicated hypothesis test, then use this value and the provided information to make a conclusion about the null hypothesis (i.e., reject or fail to reject the null hypothesis). 1.The test statistic in a left-tailed test is z = −2.05; significance level α = 8% 2. Test at the significance level α = 5% the hypothesis H0: p ≤ 0.04, given that the test statistic is z = 1.82. 3. Test at the significance level...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...
