Answer: Part 1:  10,230 cookies can be expected to be within 2 two grams of the mean, 40.

Part 2: 330 cookies will be rejected for being under 36 grams.

Step-by-step explanation:

Use the percentages given in the "Normal Distribution" on the Gaussian Curve.

For Part 1  One standard deviation on either side fo the mean is 68.2%

Multiply 15000 × .682 =  10320

For part 2:  36 is 4 less than 40.    

4 is two standard deviations. So look at the percentages listed outside the TwoStandard Deviations Below the Mean:  2.1% and 0.1%  add to get 2.2%

Multiply  15000 × 0.022 = 330
