Please provide a step-by-step explanation for each part.

Assuming that the population is normally distributed, construct a 90% condence interval for the population mean, based on the following sample size of n = 5. 1,2, 3, 4, and 17 % Change the number 17 to 5 and recalculate the condence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the condence interval. Find a 90% condence interval for the population mean, using the formula or calculator. 5 p5 (Round to two decimal places as needed.) Change the number 17 to 5. Find a 90% condence interval for the population mean, using the formula or calculator. s [.15 (Round to two decimal places as needed.) What is the effect of an outlier on the condence interval? 0 A. The presence of an outlier in the original data decreases the value of the sample mean and greatly decreases the sample standard deviation, narrowing the condence interval. 0 B. The presence of an outlier in the original data increases the value of the sample mean and greatly decreases the sample standard deviation, narrowing the condence interval. 0 c. The presence of an outlier in the original data increases the value of the sample mean and greatly inates the sample standard deviation, widening the condence interval. O D. The presence of an outlier in the original data decreases the value of the sample mean and greatly inates the sample standard deviation, widening the condence interval
