Please don't handwriting solution d. Based on the data they collected during the trial program, management found that a 95%confidence interval for the percentage of defective chips was (7%, 9%). What conclusion shouldmanagement reach about the new incentive program? Explain.O Since 8% is not in the interval, we have enough evidence that the defect rate has beendecreased.O Since 8% is in the interval, we do not have evidence that the defect rate has been decreased.e. Describe to management an advantage of decreasing the significance level.O Lowers the probability of a Type I errorO Lowers the probability of a Type II errorf. Describe to management a disadvantage of decreasing the significance level.O Raises the probability of a Type I errorO Raises the probability of a Type II errorg. Management decided to extend the incentive program so that the decision can be made on threemonths of data instead. Will the power increase, decrease, or remain the same with a larger samplesize, assuming they use the same level of significance?The power willO IncreaseO DecreaseO Stay the same A company manufacturing computer chips finds that 8% of all chips manufactured are defective.Management is concerned that employee inattention is partially responsible for the high defectrate. In an effort to decrease the percentage of defective chips, management decides to offerincentives to employees who have lower defect rates on their shifts. The incentive program isinstituted for one month. If successful, the company will continue with the incentive program.a. Write the company's null and alternative hypotheses. Make sure to include the correct parameter,sign and number.Ho:H₁:b. In this context describe a Type I error and the impact such an error would have on the company.O Management thinks the incentive program was effective, when in fact it did not lower thedefective rate from 8%.O Management thinks the incentive program did not work, when in fact it did lower thedefective rate from 8%.c. In this context describe a Type Il error and the impact such an error would have on the company.O Management thinks the incentive program was effective, when in fact it did not lower thedefective rate from 8%.O Management thinks the incentive program did not work, when in fact it did lower thedefective rate from 8%.
