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: 1967, 1666, 1607, 1622, 1749, 1805, 1590, 1921, 1822, 1675; Men: 2076, 2071, 2167, 1885, 1841, 1868, 2299, 2119. 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:
