IS – Deliverable 3 (Confidence Intervals) (Grade = F)

Dear Nelda,

See my previous feedback. Your #5 is good, but the rest is a re-do. Be sure to use the correct Excel functions.

#4, your explanations in #4 are not enough. It does not tell why we can't always use the 99% confidence interval. Use a different example to illustrate the problem.
