Homework: Read Chapter 9: In a study of systolic blood pressure of mid level management personnel from a large company was conducted. A simple random sample of 30 individuals were selected. It was found that the average was 135 with a standard deviation of 20. What is the 95% confidence interval of systolic blood pressure for the population of all mid level management personnel for this company? How about 90%? How about 99%. How large of a sample is needed for a 99% confidence interval if we wish to limit the margin of error to no more than 5 for the mid level management personnel in this company?
