Use the following information for questions:
Twenty students were randomly assigned to one of four exercise programs (5 students in each program), and the mean weight losses for the four programs were compared using one-way analysis of variance. The mean square error (MS Error) was 40. The mean weight loss for the first program was $\overline{x_1} $ = 5 pounds.
-What is a 90% confidence interval for the mean weight loss from the first program?
A) (4.44, 5.56)
B) (2.53, 7.47)
C) (0.05, 9.95)
D) None of the above
