Question

assume that a randomly selected subject is given a bone density test and those scores are normally distributed with a mean of 0 and a standard deviation of 1 Find the probability that a given score is less than 2.01 and draw a sketch of the region

Answer 1

EXPLANATION

The normal probability Table contains the probabilities to the left of z-scores.

The probability to the left of 2.01 is given in the row with 2.00 and in the column of 0.01 in the normal probability table:

P(Z<2.01) =0.9778.

The answer is 0.9778.
