Suppose that the population standard deviation for today's output is 0.14 lb (not 0.11 lb).
 
  Without doing the calculations, explain whether a correctly calculated 99 confidence interval for the mean weight of today's output would be wider than, narrower than, or the same width as that of a 99 confidence interval calculated using the population standard deviation of 0.11 lb for today's output.

Question 2

In a multiple regression model, the following statistics are given: SSE = 100, R2 = 0.995, K = 5, and n = 15. Determine the multiple coefficient of determination adjusted for degrees of freedom.
 
  A) 0.955
  B) 0.992
  C) 0.900
  D) 0.855

Answer to Question 1

A correctly calculated 99 confidence interval for the population mean would be wider than that of a 99 confidence interval calculated using the population standard deviation of 0.11 lb for today's output due to the larger standard error.

Answer to Question 2

B
