Homework Help: math - stats

Posted by barbra on Wednesday, December 19, 2012 at 12:05am.

It is believed that at least 60% of voters from a certain region in Canada favor the free trade agreement (FTA). A recent poll indicated that out of 400 randomly selected individuals, 250 favored the FTA. If we wished to perform a test to determine whether the proportion of those favoring the FTA is greater than 60%, at the 5% level of significance, we would:

Fail to reject H0 since the calculated value of the test statistic is 1.033 which is less than 1.645.

Fail to reject H0 since the calculated value of the test statistic is 1.033 which is less than 1.96.

Fail to reject H0 since the calculated value of the test statistic is 1.0204 which is less than 1.96.

Fail to reject H0 since the calculated value of the test statistic is 1.0204 which is less than 1.645.

Not need to test since everyone knows that FTA is good.
