Question: Mr. Crandall has assigned a term paper due at the end of the semester. He would like to know the average length of the paper. Assume that it follows a normal distribution. For a random sample of 16 term papers, the mean is x̄ = 14.70 pages and the standard deviation is s = 3.31 pages. Find a 98% confidence interval for the population mean length of all term papers for his class.
Plot the Student’s t distribution graph. Put a title, label the axis, put t c on the axis, and shade the area you are looking for (You will be graded on the presentation of the graph).
