In a survey of 400 childless married couples who were asked if
they plan to have children in the next 5 years, 16.5% of the men
and 22% of the women responded "Yes". Based on this survey, can it
be concluded that there is a difference in the proportion of men (
p1 ) and women ( p2 ) responding "Yes"? Use a significance level of
α=0.05 for the test.
Step 1 of 2 : Provide the p-value for the correct
test of significance. (Round to 3 decimal places.)

A survey asked, "How many tattoos do you currently have on your body?" Of the 1211 males surveyed, 193 responded that they had at least one tattoo. Of the 1089 females surveyed, 147 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let P, represent the...

Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year (USA Today, February 16, 2012). Suppose the survey sampled 200 men and 200 women. If 104 of the men replied yes and 74 of the women replied yes, are the results statistically significant in that you can conclude a greater proportion of men are expecting to get a raise or a promotion this year? (USE THE P VALUE...

A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 743 women and 713 men were independently and randomly selected, and that 383 women and 282282 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2 )? Use a significance level of α=0.1 for the test. Step 1...
