Reserve Problems Chapter 8 Section 2 Problem 2

During the nutrition research, the amount of consumed kilocalories per day was measured for 18 people – 10 women and 8 men. Results are as follows:

Women: 1962, 1842, 1588, 1911, 1779, 1603, 1758, 1771, 1874, 1974;

Men: 2097, 2560, 2328, 2399, 2420, 2292, 2263, 2047.


Calculate a 90% confidence interval on the mean for women and men separately. Assume distribution to be normal.
Round your answers to the nearest integer (e.g. 9876).

Women: Enter your answer; Women: confidence interval, lower bound ≤μ≤ Enter your answer; Women: confidence interval, upper bound
Men: Enter your answer; Men: confidence interval, lower bound ≤μ≤ Enter your answer; Men: confidence interval, upper bound
