in part 4.

Explanation / Answer

We can see from the plotted graph that the distribution is positively skewed and shows properties like the chi square distribution i.e. the mode is at the starting and more of the data is on the right side.

So, it is good to conclude the distribution as that of a chi square distribution .

The Chi Square distribution is very important because many test statistics are approximately distributed as Chi Square. Two of the more common tests using the Chi Square distribution are tests of deviations of differences between theoretically expected and observed frequencies (one-way tables) and the relationship between categorical variables (contingency tables)
