Shown below is a histogram of digits selected in California's Win 4 lottery. Each drawing involves the random selection (with replacement) of four digits between 0 and 9 inclusive.
a. What is fundamentally wrong with the graph?
b. Does the display depict a normal distribution? Why or why not? What should be the shape of the histogram?
c. Identify the frequencies, then test the claim that the digits are selected from a population in which the digits are all equally likely. Is there a problem with the lottery?
