A Random Sample of 100 Members Is Selected from the Population

question 75

Multiple Choice

A random sample of 100 members is selected from the population of UTU union members.A second sample, this one of size 200, is selected from the population of AFB union members.A third sample, also of size 200, is selected from the population of CCO union members.You use your results to fill in the table below showing the number of members in each sample who are satisfied with the representation that their union provides. You then use a chi-square test to test the null hypothesis that the three union populations represented here contain the same proportion of satisfied members.The significance level for the test is 5%.If he p-value for the sample result turns out to be .0441, what should you conclude?

• A)Don't reject the hypothesis that the proportion of satisfied members is not the same in all three union populations.
• B)Reject the hypothesis that the proportion of satisfied members is different in the three union populations.
• C)The sample provides strong evidence that the proportion of satisfied members is the same in all three union populations.
• D)The sample provides strong evidence that the proportion of satisfied members is not the same in all three union populations.
