A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 75% of the offspring resulting from this cross will have red flowers. 100 seeds from this cross were collected and germinated, and 58 plants had red petals.
A) What is the probability that the proportion of the offspring resulting from crossing will have red flowers is more than 60%?
B) Construct a 99% confidence interval for the proportion of the red flowers offspring resulting from crossing?
