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
