Suppose we gather information from a random sample of men with regard to height, foot length, and salary. Note that the first two variables follow a normal distribution quite closely, but the distribution of salary would naturally exhibit a great deal of right-skewness, due to relatively few men earning unusually high salaries. Tell which one of these distributions would not follow a normal curve:
a. Distribution of sample slope b1 for regression of foot length on height for small random samples
b. Distribution of sample slope b1 for regression of foot length on height for large random samples
c. Distribution of sample slope b1 for regression of salary on height for small random samples d. Distribution of sample slope b1 for regression of salary on height for large random samples
