Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p = 0.5 vs Ha : p > 0.5 using the sample results p? = 0.60 with n = 75 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = p-value = Conclusion: H0.

00:01 Hi, i'm david and i'm here to have you answer your question.

00:03 Now let me bring up your question here.

00:06 In the question we want to test the high -bodice testing with the noon hypothesis with the p equals 0 .15 versus the alternative hypothesis be greater than 0 .5.

00:16 Notice that with this form it will be the right -held test.

00:22 Now we've given the p -ht equals 0 -56, the n equal to the 75, the n equal to the 75.

00:30 From this one we will be able to find the test statistics.

00:33 The formula will be the phearts minus b over square root of the b times 1 minus b divided n.

00:40 We have the p hot equal to the 0 .56 b equal to the 0 .5 over the square root of the 0 .5 times 1 minus 0 .5 over n with the 75.

00:52 Now if we compute it, we will have 02525 ,000, 25 taking the square root then 0 .06 divided by the answer equal to the 1 .04.

01:11 So we have the test statistics equal to the 1 .04.

01:16 The next time we need to find the p -value because that will be the right -tow test, then the probability here, the z -cratin the test statistics, 1 .04.

01:28 To find this one, we need to find this one, we need to up the z table.

01:32 Let me copy the z table and i put the table on the right here.

01:38 Notice that the table i bring here, it has the negative score with the probability on the left tail...
