Question:
You want to estimate the average starting salary of U of C graduates. You call a random sample of 200 students who graduated in the last two years. After collecting the data, you are about to calculate the 95% confidence interval when suddenly you remember that incomes are skewed to the right. Isn’t a 95% confidence interval based on a normal curve? Was all your work in vain? Explain, making reference to the assumptions required for confidence intervals to be valid.
