Question

The mean price of computers sold at a particular store is $949 with a standard deviation of $75. The z-score of a certain computer is -0.8. What is the price of the computer?

Answer 1

the price of the computer is $889

Step-by-step explanation:

The calculation of the price of the computer is shown below

We know that

Z-score = (x - mean) ÷ standard deviation

-0.8 = (x - 949) ÷ 75

x = (-0.8 × 75) + 949

= -60 + 949

= $889

Thus, the price of the computer is $889

The above formula should be used in order to get the accurate value
