  1. For the following questions, state whether you would reject or fail to reject the null hypothesis:
  1. Critical value z > 1.96 or z < -1.96

Test value: -2.87

  1. Critical value z > 2.33

Test value: 1.85

  1. Critical value z > 2.33

Test value: -2.87

  1. Two tailed z test with an α=0.05

Test value: 1.85

  1. One tailed z test in the positive direction with an α=0.01

Test value: 8.56

Suppose I’m trying to determine whether to reject or fail to reject the null hypothesis that the country has less than or equal to 70% of people that believe the country is going in the wrong direction. If this is not true then I hypothesize that it could be larger than 70%. I’ve also taken a survey of size 50 and have found the sample percentage to be 75%. My alpha value is .05. 1.

True or False A. In hypothesis testing, if you fail to reject the null hypothesis, then you have proven the null hypothesis to be true. B. If you are more concerned about a type I error than a type II error in a hypothesis test, it would be better to use ∝= .01 than ∝= .10. C. If you have complete information for a population (from a census), it would be unnecessary and inappropriate to carry out a hypothesis test...
