Question

5. Forearm lengths of men, measured from the elbow to the middle fingertip, are normally distributed with a mean 18.8 inches and a standard deviation 1.1 inches. If I man is randomly selected, what is the probability that his forearm length is below 17 inches? 27) What are the parameters? a. Find the z-score, and construct the standard normal distribution density curve, then b. shade your seeking area. Find the probability. c.

Answer 1

Parame ters are numbers that summarize data TO an entive population. Hence the parameters Population mean, μ= 18, & are: Population standard deviation, σ 1-1 T-18.Z - HS64- -z-score = Area o intevest -1.6364- P(굿<-1. 63 64)= 0.0509 @ that his forearm length is Hence, the probobility bel0ώ 17 inches is 0,0509.
