A member of the Islip Urban Renewal Taskforce claimed that more than three quarters of new homes in the region were built with family rooms. 1. State the direction of the alternative hypothesis used to test the taskforce claim. Type gt (greater than), ge (greater than or equal to), It (less than), le (less than or equal to) or ne (not equal to) as appropriate in the box. Another committee member, who did not originally believe the claim, took a random sample of 84 houses in the area to test the validity of the claim. He found that 68 of them had family rooms. 2. Use the tables in the textbook to determine the critical value of the test statistic using a 3% level of significance. If there are two critical values, state only the positive value. 3. Calculate the test statistic, correct to two decimal places. 4. Is the null hypothesis rejected for this test? Type yes or no. 5. Regardless of your answer for 4, if the null hypothesis was not rejected, can we conclude that more than three quarters of new homes in the region were built with family rooms at the 3% level of significance? Type yes or no.

A member of the Islip Urban Renewal Taskforce claimed that more than three quarters of new homes in the region were built with family rooms.
1. State the direction of the alternative hypothesis used to test the taskforce claim. Type gt (greater than), ge (greater than or equal to), It (less than),
le (less than or equal to) or ne (not equal to) as appropriate in the box.
Another committee member, who did not originally believe the claim, took a random sample of 84 houses in the area to test the validity of the claim.
He found that 68 of them had family rooms.
2. Use the tables in the textbook to determine the critical value of the test statistic using a 3% level of significance. If there are two critical values,
state only the positive value.
3. Calculate the test statistic, correct to two decimal places.
4. Is the null hypothesis rejected for this test? Type yes or no.
5. Regardless of your answer for 4, if the null hypothesis was not rejected, can we conclude that more than three quarters of new homes in the
region were built with family rooms at the 3% level of significance? Type yes or no.
