Solved: Exact Value and Approximation Refer to Figure 6-21
Chapter 6, Problem 1(choose chapter or problem)
Exact Value and Approximation Refer to Figure 6-21 in Example 2, and refer to theMinitab display near the beginning of this section. Figure 6-21 shows the shaded region representingexactly 235 wins among 431 games. What is the shape of the corresponding regionin the Minitab display? If we use technology without an approximation, the probability ofexactly 235 wins is found to be 0.0066. If we use the normal approximation to the binomialdistribution, the probability of exactly 235 wins is found from Table A-2 to be 0.0068.Which result is better? Is the approximation off by much?
