A researcher conducts a survey of attitudes towards early prison release. She surveys 170 women and 200 men. She finds that 32% of women are in favor of early release., and 20% of men are in favor of early release. Conduct a statistical test to determine whether there is a difference in attitudes between women and men in their attitudes about early release. Use alpha= .05 to test the statistical hypothesis.

State the hypothesis in statistical terms:

What is the value of the test statistic?

State the obtained p-value:

Do you reject or fail to reject the null hypothesis:

Describe the conclusion of your test in non statistical terms:

Solutions

Expert Solution

a) H0: There is no difference in the attitudes between women and men in their attitudes about early release
H1: There is difference in the attitudes between women and men in their attitudes about early release
Let the los be alpha = 5%

b) X₁ = 0.32*170 = 54.4, X₂ = 0.20*200 = 40

Thus we conclude that there is difference in the attitudes between women and men in their attitudes about early release
