4. In this question, you will examine the distribution of this new variableAGE.

(a) Obtain the frequency histogram of the variableAGEfor the 172 observations, starting at age 20 and using intervals of 10 years. (Hint:R assumes that the right endpoint of each interval is included. Your histogram should include the left endpoints.) Paste the plot into your report. What is the shape of the histogram? Is the variableAGEdistributed evenly throughout the range of the variable? From the histogram, approximately how many Oscar winners fall in the age interval between 30 and 50 years, inclusive?

(b) Obtain the frequency histogram ofAGEfor males and females separately, using the same interval information as part
