random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O B. Ho: =4.25 H:<4.25 O A. Ho: uz4.25 H: =4.25 OC. Ho: =4.25 OD. Ho: H=4.25 H:p24.25 H:u>4.25 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. V Ho. There is v evidence to conclude that the mean of the population of student course evaluations is equal to 4.25 v correct.

Determine P-Value.

Use technology to find the​ P-value for the hypothesis test described below.   The claim is that for a smartphone​ carrier's data speeds at​ airports, the mean is μ=13.00 Mbps. The sample size is n=28 and the test statistic is t=−1.288.

The p-value for a hypothesis test turns out to be 0.00857. At a 8% level of significance, what is the proper decision? Reject H0H0 Fail to reject H0

Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 232 women, r1 = 66 responded yes. Another random sample of n2 = 198 men showed that r2 = 65 responded yes. Does this information indicate a difference (either way) between the population proportion of women and the population proportion of men who favor spending more federal tax dollars on the arts? Use ? = 0.05. State the null and alternate hypotheses.

Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 75 people and find that 62 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.78H0:p=0.78Ha:p≠0.78Ha:p≠0.78 Calculate the test statistic, rounded to 3 decimal places. z=

Consider the hypothesis test below. Ho : P1 – P2 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 100 n2 = 300 P1 = 0.27 P2 = 0.15 Use pooled estimator of p. a. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. b. With a = 0.05, what is your hypothesis testing conclusion? Select your answer -
