In a random sample of 23 people, the mean commute time to work was 30.2 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval forthe population mean u. What is the margin of error of u? Interpret the results.The confidence interval for the population meanis(Round to one decimal place as needed.)The margin of error of u is(Round to one decimal place as needed.)

We have given that, x̄ = 30.2, s = 7.2 and n = 23 Then, We will find the 99% confidence interval…

The distribution of study times for first year students follows a Normal distribution with standard deviation σσ = 54 minutes. Suppose a sample of 487 students found that the mean study time for these students was x¯x¯= 173 minutes per week.
