A university registrar wants to understand student enrollment patterns. Suppose a survey is set up where a student chooses between three different online course formats (A, B, or C). Assuming each student's choice is independent, the expected probability distribution for the chosen format is as follows: Suppose the registrar collects data from a random sample of students, and the number of students who chose each format is recorded. The results are shown below. Does the observed distribution of student choices follow the distribution expected by the registrar? Use the level of significance.
