According to example 9.17, there is no significant difference, at the 5% level, between towns A and B in their support for the candidate. However, the level a = 0.05 was chosen rather arbitrarily, and the candidate still does not know if he can trust the results when planning his campaign. Can we compare the two towns at all reasonable levels of significance? Compute the P-value of this test and state conclusions. Example 9.17 (Pre-election poll). A candidate prepared for the local elections. During his campaign, 42 out of 70 randomly selected people in town A and 59 out of 100 randomly selected people in town B showed they would vote for this candidate.
