We are given that P = population proportion of persons 20-30 years old that hold license degrees (unknown) and we are asked to test

H0: p≤0.67 versus H1: p>0.67

The observed sample proportion is pˆp^  = 61/79 = 0.772 from a random sample of size 79.

compute the following:

a)    P- value of the test

b) Probability of making Type II error and the power of this test at p= 0.87

From public records, individuals were identified as having been charged with drunken driving not less than 6 months or more than 12 months from the starting date of the study. Two random samples from this group were studied. In the first sample of 30 individuals, the respondents were asked in a face-to-face interview if they had been charged with drunken driving in the last 12 months. Of these 30 people interviewed face to face, 16 answered the question accurately. The...
