Question

assume that a randomly slelected subject is given a bone density test. those test scores are normally distributed with a mean and of 0 and a standard deviation of 1 . find the probability that a given score is less than -1.16 and draw a sketch of the region

Assume that a randomily selected subject is given a bone density test Those st scores are nomally distributed with a mean of 0 and a standard deviation of 1. Find the probabilty that a given score is less than -1 16 and drau a sketch of the regon Skelch the segion Choose the cormect graph below Ов. Ос. The probability is Round to four decimal places as needed )

Answer 1

P(X<-1.16) is to be found out.

X~N(0,1)

So P(X<-1.16)=P(Z<-1.16)=.1230244

This can be found out by running the following R code

pnorm(-1.16)

The right curve in this scenario is B.That is entire region left of -1.16.
