Q1. A study was performed on 200 college students to examine the relationship between students received regular Vitamin A supplementation and getting common colds during the month of March. 100 were
randomized to receive daily Vitamin A supplements during the month of March, and 100 students were
randomized to a placebo group (and did not receive Vitamin A) during the same month. The number of
students getting at least one cold in March was computed in the two groups, and the results are given in
the table. Determine if receiving daily Vitamin A supplements during the month and common colds are
independent?
