 If a hypothesis test is found to have power = 0.70, what is the probability that the test will ... If a hypothesis test is found to have power = 0.70, what is the probability that the test will result in a Type II error?    a. 0.30  b. 0.70  c. p> 0.70  d. Cannot determine without more information Question 2A treatment is administered to a sample of n = 9 individuals selected from a population with a mean of  = 80 and a standard deviation of  = 12 . After treatment, the effect size is measured by computing Cohen's d, and a value of d = 0.50 is obtained. Based on this information, what is the mean for the treated sample?    a. M = 6  b. M = 82  c. M = 86  d. Cannot answer without knowing the sample size Question 3A sample of n = 9 individuals is selected from a population with  = 60 and  = 6, and a treatment is administered to the sample. After treatment, the sample mean is M = 63 . What is the value of Cohen's d for this sample?    a. 0.33 c. 1.00  b. 0.50 d. 2.00 Question 4Under what circumstances can a very small treatment effect still be significant?    a. If the sample size (n) is very large  b. If the sample standard deviation () is very large  c. If the standard error of M ( M) is very large  d. All of the other factors are likely to produce a significant result. Read 35 times 2 Replies
