Z test: Yоu аre а middle schооl teаcher and you would like to compare reading comprehension scores from your students to the national average to see if there is a significant difference. You know that the national average score in reading comprehension is 80 with a standard deviation of 10 (μ = 80, σ = 10). You sample your class of 20 students and you determine that their average score on the test is 88 (M = 88). You conduct a z-test to determine whether your class scores are significantly different from the national average (Significance level α=.05). (Show your work) a. What are the null and alternative (research) hypotheses for your study? (5 points) ________________________________________________________________________________________ b. What are your critical values or z cutoffs? Note: This is a two-tailed test.
