The mass of a whiffle ball varies, usually between 40 and 50 grams. You decide to gather a random sample of whiffle balls and record the mass of each. Your data is displayed in the table below. (Units are grams.) 41.5 47.2 42.1 49.9 46.2 44.6 47.3 38.9 47.9 44.8 40.4 44.3 41.3 48.7 45.8 45.6 38.7 43.3 Checksum: 798.5 You would like to describe a "typical" whiffle ball from your data set. You decide to make several calculations describing the "center" of the data set. Find the following: a) mean b) median c) midrange d) 10% trimmed mean e) Which measure of center do you think best describes this data set. Briefly explain your choice.

High cholesterol is one of the major risk factors for heart disease. A total cholesterol reading above 190 mg/dL is considered high.A physician is concerned that a patient may be at risk for high cholesterol. In order to accurately measure the patient's average cholesterol level, the physician instructs the patient to come into the physician's office once a week for 12 weeks for a blood lipid screening. The results of the 12 measurements are listed below. 189 186 199 197 190 186 185 200 200 200 185 190 Use the critical value method to test the hypothesis that the patient's cholesterol level is greater than 190 mg/dL, using a significance level of 10%. Assume that the distribution of all cholesterol measurements from this patient is approximately normally distributed. Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If more than one critical value exists, enter the solutions using a comma-separated list.Determine the test…
