3. A restaurant association collected information on the number of meals eaten outside the home per week by young married couples. A survey of 20 couples showed the sample mean number of meals eaten outside home was 2.76 meals per week, with a S.D. of 0.75 meals per week. Construct a 90% confidence interval for the population mean. Construct a 99% confidence interval for the population mean. If the population standard deviation...

in a random sample of 8 people, the mean commute time to work was 36.5 minutes and the standard deviation was 7.4 minutes. A 90% confidence interval using the t-distribution was calculated to be (31.5,41.5). After researching commute times to work, it was found that the population standard deviation is 9.3 minutes. find the margin of error and construct a 90% confidence interval using normal distribution with the appropriate calculations for a standard deviation that is known. compare the results....
