In 1903, K. Pearson and A. Lee published the paper "On the Laws of Inheritance in Man. I. Inheritance of Physical Characters" (Biometrika, Vol. 2, pp. 357-462).
The article examined and presented data on forearm length, in inches, for a sample of 140 men, which we have provided on the WeissStats CD. Use the technology of your choice to do the following.
a. Obtain a normal probability plot, boxplot, and histogram of the data.
b. Is it reasonable to apply the t-interval procedure to the data? Explain your answer.
c. If you answered "yes" to part (b), find a 95% confidence interval for the mean forearm length of men. Interpret your result.
