6-9 multiple choice please

Question 6 (1 point) Suppose we want to test H0: p = 100 against H3: [.1 > 100, based on a random sample of 65, a standard deviation of 25, and a sample mean of 105. Check all of the correct decisions: C] a) not reject H0 at or= 0.10. C] b) reject H0 at ct= 0.05. C] c) reject H0 at or= 0.10. C] d) reject H0 at u= 0.07. C] e) not reject H0 at u= 0.05. E] f) not reject H0 at u= 0.07. Question 7 (1 point) Suppose we want to test H0: p = 80 against Ha: u =2 80, based on a random sample of 50. a standard deviation of 18. and a sample mean of 76. Check all of the correct decisions: C] a) reject H0 at {X 0.10. C] b) reject H0 at IX 0.07. C] c) reject H0 at or 0.05. C] d) not reject H0 at o: 0.10. C] e) not reject H0 at or 0.05. E] f) not reject H0 at or 0.07. Question 8 (1 poi nt) Let x1,....xn be a random sample from some population with 2:12 = 34334. Ex = 3446. and n= 359. Suppose I want to test the hypothesis H0: p. = 3 against Ha: p. > 8 at a significance level of 0: = 0.05. Then what is the z-statistic (pick the best value) and the conclusion. ie. reject or not reject H0. C] a) 26.2869 C] b) 36.4016 C] c) 6.0575 C] 6) 16.1722 C] e) reject H0 E] f) not reject H0 Question 9 (1 point) Let x1,....xn be a random sample from some population with 2:12 = 34334. Ex = 3446, and n= 359. Suppose I want to test the hypothesis H0: u = 9.79 against H3: 11 == 9.79. Please select all the correct choices: C] a) not reject H0 at or = 0.06. C] b) reject H0 at 01 = 0.05. C] c) reject H0 at 0: = 0.06. C] d) reject HtJ at o: = 0.10. C] e) not reject H0 at 0: = 0.10. E] f) not reject H0 at 01 = 0.05
