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 104.32 ± 3.92 is:.
a) actually a 90% confidence interval.
b) actually a 99% confidence interval.
c) not very reliable.
d) very reliable.
