Solve the problem.A researcher conducts a hypothesis test on a populationproportion. Her null and alternative hypothesis are Ho: p= 0.6 and Ha: P < 0.6. The test statistic and p-value forthe test are z = -1.51 and p-value = 0.0655. For asignificance level of a = 0.05, choose the correctconclusion regarding the null hypothesis.O None of these.O There is sufficient evidence to warrant rejection of the nullhypothesis.There is insufficient evidence to warrant rejection of thenull hypothesis.STEP 1/3RoutinWe're findianswer youIn the meaDIVE DEEP
