Goodness-of-Fit Test · Try It 2

Teachers want to know which night each week their students are doing most of their homework. Most teachers think that students do homework equally throughout the week. Suppose a random sample of 56 students were asked on which night of the week they did the most homework. The results were distributed as in.

$$\begin{array}{cccccccc}& \text{Sunday}& \text{Monday}& \text{Tuesday}& \text{Wednesday}& \text{Thursday}& \text{Friday}& \text{Saturday}\\ \text{Number of Students}& \text{11}& \text{8}& \text{10}& \text{7}& \text{10}& \text{5}& \text{5}\end{array}$$
From the population of students, do the nights for the highest number of students doing the majority of their homework occur with equal frequencies during a week? What type of hypothesis test should you use?

Its source prints no answer for this problem, so there's nothing to check against.
