Use the given degree of confidence and sample data to construct a confidence interval for the population mean Assume that the population has a normal distribution. Thirty randomly selected students took the calculus final. If the sample mean was 76 and the standard deviation was 77construct a 99% confidence interval for the mean score of all students. 73.61 < y < 78.39; 72.54 < mu < 79.46; 72.13 < mu < 79.87; 72.14 < mu * 79.89
