Suppose a random variable is hypothesized to be normally distributed with a mean of 0 and a standard deviation of 1. A random sample of 200 observations of the variable yields frequencies in the intervals listed in the table shown below. Do the data provide sufficient evidence to contradict the hypothesis that x is normally distributed with m = 0 and s = 1? Use the technique developed in Exercise 13.67.
