In each of Exercises, we have provided a distribution and the observed frequencies of the values of a variable from a simple random sample of a population. In each case, use the chi-square goodness-of-t test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution.

Distribution: 0.5, 0.3, 0.2

Observed frequencies: 147, 115, 88

Significance level = 0.01
