c) Suppose we want to determine what proportion of all first-year students plan to participate in an internship. A random sample of 100 students are asked if they plan to participate in an internship and a 95% confidence interval is generated as (0.38, 0.42). Interpret this confidence interval in the context of the problem. [6 points]
