Depending on which place value you1l round to, the final result will vary.Explanation / Answer
Q. 1 The type I error
Option D is correct. Type I error always means that rejecting the null hypothesis when it is true so here Option D entails that reject the null hypothesis that the percentage of high school students who graduate is less than 55% when that percentage is actually less than 55%.
Q. 2 Type II error
Option D is correct. Type II error mean that failed to reject the null hypothesis even if it is correct. SO Option D entails that we failed to reject the null hypothesis that the percentage of high school students who graduate is less than 55% when that percentage is actually equal to 55%.
Q.3 a. p >= 0.45
b. Null HYpothesis : H0: p < 0.45
Alternativve Hypothesis : Ha : p >= 0.45
Q.4 Here p == 0.19
margin of error = 0.01 = critical test static * standard error of sampling
0.01 = Z0.05 sqrt [ p(1-p)/N]
0.01 = 1.96 * sqrt [ 0.19 * 0.81/n]
n = 5912
