3) Use technology to solve the following problem: A survey reported that in a recent year,the mean serum cholesterol level in milligrams per deciliter for U.S. adults was 1993)with a standard deviation of 35. A random sample of 104 adults was chosen. What isthe probability that the mean cholesterol level is less than 198?C) 0.3854A) 0.5114B) 0.6146D) 0.4886

The mean is 199 and the standard deviation is 35.

A bottled water distributor wants to determine whether the mean amount of water contained in 1-gallon bottles purchased from a nationally known water bottling company is actually 1 gallon. You know from the water bottling company specifications that the standard deviation of the amount of water is 0.03 gallon. You select a random sample of 45 bottles, and the mean amount of water per 1-gallon bottle is 0.996 gallon. Complete parts (a) through (d) below. a. Is there evidence that the mean amount is different from 1.0 gallon? (Use a = 0.01.) Let u be the population mean. Determine the null hypothesis, Ho, and the alternative hypothesis, H, . Ho: H What is the test statistic? ZSTAT = (Round to two decimal places as needed.) What is/are the critical value(s)? (Use a = 0.01.) (Round to two decimal places as needed. Use a comma to separate answers as needed.) What is the final conclusion? O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the mean…
