t is believed that the percent of convicted felons who have a history of juvenile delinquency is 70%. Isthere evidence to support the claim that the actual percentage is more than 70% if out of 200 convictedfelons, we find that 154 have a history of juvenile delinquency? Set the level of significance at � = 0.05a) Write the null and alternative hypotheses.b) Check the conditions to conduct the hypothesis test for the population proportion.c) Find the z test statistic and the p-value.d) Sketch the z curve indicating the z test statistic and the p-value.e) Should you reject or fail to reject the null hypothesis based on the p-value obtained in the previous part?Why?f) State your conclusion from the test

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
