Answer:
46.72%.
Step-by-step explanation:
We have been given that the number of boxes of supplies received weekly is normally distributed with a mean of 200 and a standard deviation of 20. We are asked to find the number of boxes of supplies that arrive will be greater than 210 or less than 180.
We will use z-score formula and normal distribution table to solve our problem.
Let us find z-score corresponding to normal score 210.
Using normal distribution table, we will get:
Therefore, 46.72% of the time the number of boxes of supplies that arrive will be greater than 210 or less than 180.
