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. A simple random sample of 25 children from this population is taken and each is given the WISC. The mean of the 25 scores is = 104.32. Suppose a histogram of the 25 WISC scores is the following. Based on this histogram, we would conclude that a 95% confidence interval of...
