Twenty-one mature flowers of a particular species were dissected, and the number of stamens and carpels present in each flower were counted

a. Is there sufficient evidence to claim a linear relationship between these two variables at a = 0.05
b. What is the relationship between the number of stamens and the number of carpels in this variety of flower?
c. Is the slope of the regression line significant at a = 0.05?
d. Give the 95% prediction interval for the number of carpels that one would expect to find in a mature flower of this variety if the number of stamens were 64.
