The 68‑95‑99.7 rule tells us how to find the middle 68%, 95%, or 99.7% of a Normal distribution. Suppose we wanted to find numbers A and B, so that the middle 80% of a standard Normal distribution lies between A and B, where A is less than B. Which of the answers below is not true of A and B? A: 10% of the distribution lies above B. B: B is approximately 1.28. C: 20% of the distribution lies below A. D: To get the middle 80%, we would have ?=−?.
