Explanation / Answer

Statcrunch Steps:

Stat --> Goodness of Fit --> Chi - square Tes --> Select number column for observed --> Marked All cells in equal proportion for expected --> Compute

The output will be:

closemaximize

Chi-Square goodness-of-fit results:
Observed: Number
Expected: All cells in equal proportion

Hence,

Test statistic = 69.2

p - value = 0

Reject Ho. There is sufficient evidence to warrant rejection of the claim that the four categories are equally likely. The result suggests to support the expectation that the frequency for the first category is dispropotionately high.
