A personnel manager has found that, historically, thescores on aptitude tests given to applicants for entry-level positions follow a normal distribution with standarddeviation 24.09 points. A random sample of 11 testscores from the current group of applicants had a meanscore of 70.76 points. Based on these sample results, astatistician found for the population mean a confidenceinterval extending from 59.7923 to 81.7277 points. Findthe confidence level (as a value between zero and one) ofthis interval.

Answer Sample size [n] = 11 Sample mean =[x] =70.76 Standard deviation =24.09 Confidence interval =…

A drug store chain provides an app to its customers to track their shopping habits. One statistic the app tracks is the amount of money the customer saves by purchasing sale items. The company's sales team pulls data from the previous year for a random sample of 50 customers. They find that the mean amount of money saved by these customers in the previous year is $154 with a standard deviation of $26. (a) Construct a 99% confidence interval for the true mean amount of money saved by all customers in the previous year by purchasing sale items (b) The sales team would like to repeat this study with the goal of obtaining a smaller margin of error. Propose two changes that would decrease the margin of error. What are potential drawbacks if those changes are implemented?
In a test of the effectiveness of garlic for lowering cholesterol, 42 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.9 and a standard deviation of 15.3. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment.

A company that manufactures baseball bats believes that its new bat will allow players to hit the ball 30 feet farther than its current model. The owner hires a professional baseball player known for hitting home runs to hit ten balls with each bat and he measures the distance each ball is hit to test the company's claim. The results of the batting experiment are shown in the following table. Construct a 90 % confidence interval for the true difference between the mean distance hit with the new model and the mean distance hit with the older model. Assume that the variances of the two populations are the same. Let Population 1 be the distances of balls hit with the new model baseball bat and Population 2 be the distances of balls hit with the old model.
