answer please can simplify process
Two experimental diets, designed to add weight to malnourished adults in developing countries, are being tested. The following sample data for weight gain after 6-weeks on the diet (in kg) was obtained (assume normally distributed data): N4 = 8, mean = 5.80, S4 = 1.613 for Diet A and n2 = 9, mean = 7.27, 92 = 0.99 for Diet B. You use the pooled t-test to test whether Diet B is better than Diet...
