In one of Mendel’s hybridization experiments with peas, the probability of offspring peas having green pods is ¾ or 0.75. Assume that whether offspring pea has green pods is independent of whether the green pod is a different color.

  1. Find the probability that exactly 13 out of 20 offspring peas will have green pods.
  1. Find the probability that 13 or fewer out of 20 offspring peas will have green pods.

According to a Consumer Report, the mean replacement time of a television is 8.2 years with a standard deviation of 1.1 years. The distribution of TV replacement times is approximately Normal. Use a table or technology for each question. Include an appropriately labeled Normal curve for each part. There should be three separate curves.

  1. What is the probability that a person will replace their TV after 12 years?

  1. What is the probability that a person will replace their TV before 3 years?

  1. What is the probability that a person will replace their TV between 6 and 10 years?

A scientist conducted a hybridization experiment using peas with green pods and yellow pods. He crossed peas in such a way that​ 25% (or 143​) of the 572 offspring peas were expected to have yellow pods. Instead of getting 143 peas with yellow​ pods, he obtained 148. Assume that the rate of​ 25% is correct. a. Find the probability that among the 572 offspring​ peas, exactly 148 have yellow pods. b. Find the probability that among the 572 offspring​ peas,...

3. When Gregor Mendel conducted his famous hybridization experiments with peas, one such experiment resulted in 580 offspring peas, with 26.2% of them having yellow pods. According to Mendel’s theory, 25% of them should have yellow pods. Use a .05 significance level to test the claim that the proportion of peas with yellow pods is 25%. a. Check your assumptions (SINS).    b. Set up the null and alternative hypotheses. ?0:______________________ ?1:______________________ c. You will run the following type of...
