Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution. Thirty randomly selected students took the calculus final. If the sample mean was 95 and the standard deviation was 6.6, construct a 99% confidence interval for the mean score of all students. A. 91.68 < μ < 98.32 B. 92.03 < μ < 97.97 C. 92.95 < μ < 97.05 D. 91.69 < μ < 98.31

Use the given sample data and confidence level. In each case, (a) find the best point estimate of the population proportion p; (b) identify the value of the margin of error E; (c) construct the confidence interval; (d) write a statement that correctly interprets the confidence interval. From a KRC Research poll in which respondents were asked if they felt vulnerable to identify theft: $n = 1002 , x = 531$ who said “yes.” Use a $95\%$ confidence level.
