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?
