b. Assume that sample mean x and sample standard deviations remain exactly the same as those you just calculated but that are based on a sample of n = 25 observations. Repeat part a What is the offect of increasing the sample size on the width of the confidence intervale? The confidence interval is (5.13,6 87). (Rounid to two decimal places as needed.) What is the effect of the sample size on the width of the confidence intervall? * As the sample size increases, the width decreases *. As the sample size increases, the width increases As the sample size increases, the width stays the same
