Question 17: A random sample of 100 scores was drawn from a normal distribution. The sample mean was 57 and the estimated standard error of the mean was 20. The null hypothesis is that the scores were drawn from a distribution with a mean of ? = 67, and the alternative hypothesis is that ? ? 67. Assuming ? = .05, the null hypothesis should be Rejected Accepted One tailed Retained

A random sample of 100 scores was drawn from a normal distribution. The sample mean was 57 and the estimated standard error of the mean was 20. The null hypothesis is that the scores were drawn from a distribution with a mean of μ = 67, and the alternative hypothesis is that μ ≠ 67. Assuming α = .05, the null hypothesis should be Rejected Accepted One tailed Retained
