18.24 (EX) More nutritious corn 1/6: Ordinary corn doesn't have as much of the amino acid lysine as animals need in their feed. Plant scientists have developed varieties of corn that have increased amounts of lysine. In a test of the quality of high-lysine corn as animal feed, an experimental group of 20 one-day-old male chicks ate a ration containing the new corn. A control group of another 20 chicks received a ration that was identical except that it contained ordinary corn. Here are the weight gains (in grams) after 21 days:

Question
give a 90% confidence interval for the difference in mean weight gain after 21 days for chicks fed high-lysine corn or ordinary corn.
Is there good evidence that chicks fed high-lysine corn gain more weight? Let μ1 and μ2 be the mean weight gains of chicks fed high lysine corn and ordinary corn, respectively. State the hypotheses.
What is the test statistic? and P-value
