Use the data from Example 8.11 involving citizens opinions about a bond proposal, reproduced as follows. Is there evidence of a difference in the proportions favoring the proposal for the two sections of the city?

1. Select stat ➤ TESTS ➤ 6:2-PropZTest… Enter the values for n1, n2, x1, and x2 on the appropriate lines, and make sure that the alternative hypothesis is set to p ≠ p 1 2.
2. When you move the cursor to Calculate and press enter, the results (z=1.37 and p-value 5 0.171) will appear, shown on the screen in Figure 9.19(b). The results are not significant. There is no evidence that the citizens in the developing section have a different opinion than those in the rest of the city.
