Statistics- We want to test the hypothesis that at least 85% of drivers

QUESTION

We want to test the hypothesis that at least 85% of drivers on a freeway violate the speed limit. In a random sample of n = 1,100 vehicles, 83% violated the speed limit. Compute the test statistic. State the null and alternative hypotheses and the decision rule. Use α = 0.05. a TS = 1.85 Reject H₀. The proportion of violators is less than 0.85. b TS = 1.85 Do not reject H₀. The proportion of violators is not less than 0.85. c TS = 1.45 Do not reject H₀. The proportion of violators is not less than 0.85. d TS = 1.45 Reject H₀. The proportion of violators is less than 0.85.
