You have measured the proportion of acceptable items for two different suppliers. 9000 out of 10000 items from Supplier A were acceptable; 95 out of 100 items from Supplier B were acceptable.
Conduct a two-sided hypothesis test with alpha = 0.1 that the proportion of acceptable items is the same for both suppliers versus the alternative that it is not.
What is the value of the test statistic, ?
What is the value associated with the critical region, ?
If you would reject the null hypothesis, enter 1;
If you would fail to reject the null hypothesis, enter 2.
