Use technology or a z-score table to answer the question.

the expression p(z < 2.87) represents the area under the standard normal curve below a given value of z.

what is p(z < 2.87)?

a. 0.0021

b. 0.0027

c. 0.9973

d. 0.9979

D

Step-by-step explanation:

I usually use a z-score table, but you can do this with a calculator.

If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column.  Then we find the hundredths digit in the top row (0.07).  Where they intersect is P(z < 2.87).

P(z < 2.87) = 0.9979
