Answer to Question 1

FALSE

Answer to Question 2

The probability, , of making a Type II error for any given population proportion P1 included in H1 is found as follows:
1. From the test decision rule, find the range of values of the sample proportion leading to failure to reject the null hypothesis.
2. Using the value P1 for the population proportionwhere P1 is included in the alternative hypothesisfind the probability that the sample proportion will be in the nonrejection region determined in step 1 for samples of n observations when the population proportion is P1.
