same cities in 2014. We would like to use these data to compare average air quality between the two years. Which of the following tests is the most appropriate? independent samples t-test with two-sided alternative hypothesis paired t-test with two-sided alternative hypothesis independent samples t-test with one-sided alternative hypothesis paired t-test with one-sided alternative hypothesis 8. We are testing the following hypotheses: Họ : µ1 = 42 HẠ : 41 # 42 The sample sizes are nį = 20 and ng = 40. Your friend who is working on this hypothesis test calculates a z statistic, Z = 2.5. Which of the following is true? p-value is approximately 0.006. O p-value is approximately 0.012. She should be using an F statistic instead of a Z statistic. She should be using a T statistic instead of a Z statistic.
