The scores of a certain population on the Wechsler Intelligence Scale for Children (WISC) are thought to be normally distributed with mean μ and standard deviation σ = 10. I wish to test whether the mean for this population differs from the national average of 100, so I the hypotheses H0: μ = 100 and Ha: μ ≠ 100 based on an SRS of size 25 from the population. I calculate a 95% confidence interval for μ and find it to be 100.76 to 106.24. Which of the following is true?
