Ответ:
The weight of a box of candies is 18 oz
Option 2 is correct.
Step-by-step explanation:
Given: The weights of boxes of candies produced in a factory are normally distributed with a mean weight of 16 oz and a standard deviation of 1 oz.
Formula:![z=\dfrac{x-m}{\sigma}](/tpl/images/0217/2135/e1af4.png)
Mean: m = 16 oz
z-score: z = 2
Standard Deviation:![\sigma = 1 oz](/tpl/images/0217/2135/c7434.png)
Substitute the value into formula.
Hence, The weight of a box of candies is 18 oz
