4: Probability and Probability Distributions

b From Exercise 6.11b, we found that the 95th percentile of the standard normal (z) distribution is Since , solve for x to find the 95th percentile for the pulse rates: c The z-score for is and . The z-score is between 2 and 3; the probability of observing a value this large or larger is quite small. This pulse rate would be somewhat unusual. ................
