In a recent survey, 24 out of 40 randomly selected voters indicated that they would vote for the politician. (You may find it useful to reference the appropriate table: z table or t table) a. Select the null and the alternative hypotheses. V Hg: p = 0.50; HA: p + 0.50 O Hg: p 0.50; HA: p > 0.50 O Hg: p 2 0.50; HA: p < 0.50 b. Calculate the sample proportion.

The student writes: "Because the p-value is less than 0.5, we reject the null hypothesis." What is wrong with the student's conclusion? Group of answer choices The student should have stated the data prove Ha is true. The student should have stated the data prove H0 is true. The p-value should be compared with the mean, not the hypothesized value of p. The p-value should be compared with the standard deviation, not the hypothesized value of p. The p-value should be compared with a significance level such as α = 0.05, not the hypothesized value of p.arrow_forward

Polls show that about 69% of American adults followed the news about the political crisis and demonstrations in Egypt closely during the first couple weeks following the start of the uprising. Among a random sample of 30 high school students, it was found that only 17 of them followed the news about Egypt closely during this time.
