SOLVED: Ha: π = 0.50.a. What happens when you conduct the Wald test, which uses the estimated standarderror in the z test statistic?b. Find the 95% Wald confidence interval (1.3) for π. Is it believable?c. Conduct the score test, which uses the null standard error in the z test statistic.Report and interpret the P-value.d. Verify that the 95% score confidence interval equals (0.0, 0.133). (This is similarto the interval (0.0, 0.137) obtained with a small-sample method of Section 1.4.3,inverting
