In: Statistics and Probability
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:
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
