The scores of a certain population on the Wechsler Intelligence Scale for Children (WISC) are thought to be Normally distributed, with mean u and standard deviation o = 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 i = 104.32. Based on these data, a 95% confidence interval for µ is: 104.32 + 3.29. O 104.32 ± 3.92. O 104.32 ± 0.78. O 104.32 ± 19.6.
