Learning Goal: I’m working on a mathematics multi-part question and need an explanation and answer to help me learn.
A random sample of 188 students at a large dormitory cafeteria showed that 66 choose the vegetarian option as their meal plan. let p represent the proportion of students selecting the vegetarian option as a meal plan.
a. What is a point estimate for p?
b. Find 99% confidence interval for p?
c. Interpretation: What does the confidence interval you just computed mean in the context of this application?
d. Check the requirements to compute the confidence interval, we used a normal approximation. Does this seem justified?
