Assume both samples are SRS from the population of one-day-old male chicks. According to the stem plot, can we safely apply the CLT? A) The back-to-back stem and leaf plot shows that both distributions are close to normal. But the sample size is too small, so the CLT will not apply. B) The back-to-back stem and leaf plot shows that both distributions are close to normal. With the sample size we have here, the CLT will apply. C) The back-to-back stem and leaf plot shows that both distributions are far from normal. With the sample size we have here, the CLT will apply. D) The back-to-back stem and leaf plot shows that both distributions are far from normal. The CLT will not apply.

Assume both samples are SRS from the population of one-day-old male chicks. According to the stem plot, can we safely apply the CLT?

A) The back-to-back stem and leaf plot shows that both distributions are close to normal. But the sample size is too small, so the CLT will not apply.

B) The back-to-back stem and leaf plot shows that both distributions are close to normal. With the sample size we have here, the CLT will apply.

C) The back-to-back stem and leaf plot shows that both distributions are far from normal. With the sample size we have here, the CLT will apply.

D) The back-to-back stem and leaf plot shows that both distributions are far from normal. The CLT will not apply.
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:

Round the data to the 10's place and make a back-to-back stem plot while splitting the stem.
