9.41 Plant Genetics 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. To test this claim,
100 seeds from this cross were collected and germi-
nated and 58 plants had red petals.

a. What hypothesis should you use to test the geneti-
cist's claim?
b. Calculate the test statistic and its p-value. Use the
p-value to evaluate the statistical significance of the
results at the 1% level.
