Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p = 0.5 versus Hy:p>0.5 n= 100; x = 65, a = 0.1 Is npo (1-Po) 2 10? No Yes Use technology to find the P-value. P-value = (Round to three decimal places as needed.) the null hypothesis, because the P-value is than a. Reject Do not reject

Consider the hypothesis test below. Ho: P 1-2250 Ha: P 1-22 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 ni = 200 n2 = 400 P1 = 0.26 P2 = 0.16 -a. What is the value of the test statistic (to 2 decimals)? b. What is the p-value (to 4 decimals)? c. With a = .05, what is your hypothesis testing conclusion? Select
