In the past, 25% of the town residents participated in the school board elections. the town officials recently undertook an extensive campaign to encourage registered voters to participate in the election process. they are interested in determining whether the promotional campaign actually increased the proportion of voters. the correct set of hypotheses is

a. h0: p < .25; ha: p ≥ .25
b. h0: p ≥ .25; ha: p < .25
c. h0: p > 25; ha: p ≤ 25

H0: p ≤.25 Ha: p >.25

Step-by-step explanation:

One choice is missing. Correct choices are:

a. H0: p > 25 Ha: p ≤ 25

b. H0: p ≥ .25 Ha: p <.25

c. H0: p <.25 Ha: p ≥ .25

d. H0: p ≤.25 Ha: p >.25

Town officials are interested in determining whether the promotional campaign actually increased the proportion of voters.

Null hypothesis should assume that the promotional campaign didn't increase the proportion of voters. That is H0: p ≤.25

And alternative hypothesis should assume that the promotional campaign actually increased the proportion of voters. That is Ha: p >.25

If the sample proportion is found significant under null hypothesis at a specified significance level, then null hypothesis can be rejected and can be concluded that there is significant evidence that the promotional campaign actually increased the proportion of voters.
