Use the data from Example 8.11 involving citizens opinions about a bond proposal, reproduced here.

Suppose that the citizens in the developing section of the city have no opinion about this proposal, so that they are equally likely to favor as oppose the proposal. Test : .5 0 H p5 against : .5 a H p≠ .
1. Select stat ➤ TESTS ➤ 5:1-PropZTest… Enter the value for .5 0p 5 , enter the values for x and n on the appropriate lines, and make sure that the alternative hypothesis is set as p ≠ p0.
2. When you move the cursor to Calculate and press enter, the results (z=3.68 and p-value50.000) will appear, shown on the screen in Figure 9.19(a). The results are highly significant. There is evidence that the citizens in the developing section DO have an opinion about this proposal!
