I'm not sure how to work out this question:
The Australian Medical Association believed that the Health Minister's recent statement claiming that at least 80% of doctors supported the reforms to Medicare was incorrect. The Association's President suggested the best way to test this was to survey 200 members, selected through a random sample, on the issue. She indicated that the Association would be prepared to accept a Type I error probability of 0.02.
1. State the direction of the alternative hypothesis for the test.
2. Using the tables, state the absolute value of the test statistic
and determine the lower boundary 3._____, and the upper boundary 4______.
of the region of non-rejection in terms of the sample proportion of respondents (as %) in favour of the reforms. If there is no (theoretical) lower bound, type lt in box 3, and if there is no (theoretical) upper bound, type gt in box 4. State the numerical value(s) correct to one decimal place.
5. If 137 of the survey participants indicated support for the reforms, is the null hypothesis rejected for this test? Type yes or no.
6. If the null hypothesis is rejected, can the Association claim that the Health Minister's assertion is incorrect at the 2% level of significance on the basis of this test?
Thank-you very much for your help!!
