When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 907 peas, with 690 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3/4 probability that a pea will have a red flower, we would expect that 680.25 (or about 680) of the peas would have red flowers, so the result of 690 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 690 or more peas with red flowers. b. Is 690 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/4 of peas will have red flowers?

Question
When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of
probability that a pea will have a red flower, we would expect that
907
peas, with
690
of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a
3/4
680.25
(or about
680)
of the peas would have red flowers, so the result of
690
peas with red flowers is more than expected.a. If the scientist's assumed probability is correct, find the probability of getting
690
or more peas with red flowers.b. Is
690
peas with red flowers significantly high?c. What do these results suggest about the scientist's assumption that
3/4
of peas will have red flowers?Expert Solution
