Test the hypothesis using the Pvalue approach Be sure to ver

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Is npo (1 ? p 0)> or = to 10? Yes NO Use technology to find the P-value. P-value (Round to three decimal places as needed.) because the P-value is than a. Reject the null hypothesis, Do not reject the null hypothesis,

Solution

Yes.

The test statistic is

Z=(phat-p)/sqrt(p*(1-p)/n)

=(87/150-0.64)/sqrt(0.64*(1-0.64)/150)

=-1.53

The p-value= P(Z<-1.53) =0.063 (from standard normal table)

Do not reject the null hypothesis because the P-value is larger than a
