Question

Test whether males are less likely than females to support a ballot initiative, if 23% of a random sample of 49 males plan to vote yes on the initiative and 33% of a random sample of 49 females plan to vote yes.

Use subscripts 1 for males who plan to vote yes and 2 for females who plan to vote yes.

(a) Find the relevant sample proportions in each group and the pooled proportion.

Round your answers to three decimal places, if necessary.

p-hat 1 = 0.23 (already answered this part correctly)

p-hat 2 = 0.33 (already answered this part correctly)

p-hat = ______ (Incorrect answers so far: 0.280, 0.28 )

b)State the null and alternative hypotheses.

H0: p1 = p2 vs Ha: p1does not equal p2 (already answered this part correctly)

(c) Give the test statistic and the p-value.

Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.

test statistic = -1.10 (already answered this part correctly)

p-value = _____ (Incorrect answers so far: 0.864, 0.865, 0.359 )
