Please answer parts A & B, the data table is in the picture below. Thank you! :)
Which one of the following statements about confidence intervals is false? Given the same sample of data, a 99% confidence interval will be wider than a 95% confidence interval. The size of the population affects the width of a confidence interval. The sample statistic determines the center of the confidence interval. The value of z* affects the width of a confidence interval. The general format of a confidence interval is “sample statistic ± margin of error.”
Construct a 95% confidence interval for the population mean, based on each of the sets of data below, assuming that the population is normally distributed. Explain why these data sets produce different confidence intervals even though they have the same mean and range. Set 1: 1 1 1 1 8 8 8 8 A Full data set Set 2: 1 2 3 4 5 6 7 8 Construct a 95% confidence interval for the population mean for set 1.

2.3 The width of a confidence interval is a measure of its precision. The narrower the confidence interval, the more precise is the interval estimate, and vice versa. Describe any three aspects that influence the precision of the width of a confidence interval of a single population mean.
If n = 15, ¯xx¯ = 36, and s = 12, construct a confidence interval at a 90% confidence level. Assume the data came from a normally distributed population. Give your answers to three decimal places.
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
