Distribution: 0.5, 0.3, 0.2;,Observed frequencies: 45, 39, 16;,Significance level = 0.01,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-fit test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution.
