Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

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

The expression P(z < 1.87) represents the area under the standard normal curve below the given value of z.

What is P(z < 1.87)?

Answer 1

Answer: d) 0.9693

Explanation:

refer to the z-table attached.

The table shows the percent from the MEAN. The percent below the mean is 50% so that needs to be added to the value in the table.

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).

The value is 0.4693 --> add 0.5 to that value to get 0.9693.
