Chapter 9.4, Problem 13MS
Dizzy Lincoln. The text describes a penny-spinning experiment. The graph below shows the theoretical distribution of the number of heads occurring for 1000 spins. Suppose you repeat the experiment and obtain heads 412 times. Locate 400 on the horizontal axis below. Does this look like an extremely rare occurrence? What if you obtained 550 heads? What about 650 heads?
