Construct a 95% confidence interval for data set III. The lower bound is 93.58 The upper bound is 104.09 (Round to two decimal places as needed) (c) What impact does the sample size n have on the width of the interval? A. As the sample size increases, the width of the interval increases. B. The sample size has no impact on the width of the interval c. As the sample size increases, the width of the interval decreases (d) Suppose that the data value 106 was accidentally recorded as 061. For each data set, construct a 95% confidence interval using the misentered data. Construct a 95% confidence interval for data set I The lower bound is 73.82 The upper bound is 112.43 (Round to two decimal places as needed.) Construct a 95% confidence interval for data set II. The lower bound is The upper bound is (Round to two decimal places as needed)
