Question

When a scientist conducted a genetics experiments with​ peas, one sample of offspring consisted of 915 peas, with 715 of them having red flowers. If we​ assume, as the scientist​ did, that under these​ circumstances, there is a 3 divided by 43/4 probability that a pea will have a red​ flower, we would expect that 686.25 (or about 686​) of the peas would have red​ flowers, so the result of 715 peas with red flowers is more than expected.

a. If the​ scientist's assumed probability is​ correct, find the probability of getting 715 or more peas with red flowers.

b. Is 715 peas with red flowers significantly​ high?

c. What do these results suggest about the​ scientist's assumption that 3 divided by 43/4

of peas will have red​ flowers?
