Consider the following hypotheses:Ho: PHAP= 0.400.40A sample of size 200 was collected out of which there were 56successes. Suppose we conduct a test at the 5% significance level.a. Determine the critical values: ±315b. Calculate the test statistic: 0.00001c. Choose the correct decision and the correct reasoning:Fail to reject the null hypothesis since the test statistic fallsoutside the critical values.O Fail to reject the null hypothesis since the test statistic fallswithin the critical values.O Reject the null hypothesis since the test statistic falls outsidethe critical values.O Reject the null hypothesis since the test statistic falls within thecritical values.

The question is about hypothesis testingGiven :Selected no. of samples ( n ) = 200No. of successes…

Answered: Consider the following hypotheses: Ho:…
