The average number of moves a person makes in his or her lifetime is 12. If the standard deviation is 3.2, find the probability that the mean of a sample of 36 people is less than 10.

0.0001

Step-by-step explanation:

The average number of moves a person makes in his or her lifetime is 12.

We want to find the probability that the mean of a sample of 36 people is less than 10, if the standard deviation is 3.2.

We calculate the z-score using the formula:

We substitute the values to get:

We simplify to get;

From the standard normal distribution table we read -3.7 under 5 to obtain the area to the left of -3.75 as 0.0001
