Question

Determine if the conditions required for the normal approximation to the binomial are met. If so, calculate the test statistic, determine the critical value(s), and use that to decide whether there is sufficient evidence to reject the null hypothesis or not at the given level of significance.

H_(0):p=0.85
H_(1):p!=0.85
hat(p)=0.771
n=120
\alpha =0.05

a. Calculate the test statistic.

Z=

Round to two decimal places if necessary Enter 0 if normal approximation to the binomial cannot be used b. Determine the critical value(s) for the hypothesis test. Round to two decimal places if necessary Enter 0 if normal approximation to the binomial cannot be used c. Conclude whether to reject the null hypothesis or not based on the test statistic. Reject Fail to Reject
