Question
Chocolate chip cookies have a that is approximately normal with a mean of 24.4 chocolate chips per cookie and a standard deviation of 2.1 chocolate chips per cookie. Find P_1 and P_99. How might those values be helpful to the producer of the chocolate chip cookies? P_1 = 19.5 (Round to one decimal place as needed.) P_99 = 29.3 (Round to one decimal place as needed.) How might those values be helpful to the producer of the chocolate chip cookies? Choose the correct answer below. A. The values can be used to identify cookies with an unusually low or high number of chocolate chips, so those numbers can be used to monitor the production process to ensure that the numbers of chocolate chips stays within reasonable limits. B. The values can be used to identify cookies with an average number of chocolate chips, so those numbers can be used to monitor the production process to ensure that the numbers of chocolate chips stays below P_1. C. The values can be used to identify cookies with an average number of chocolate chips, so those numbers can be used to monitor the production process to ensure that the numbers of chocolate chips stays within reasonable limits. D. The values can be used to identify cookies with an unusually low or high number of chocolate chips, so those numbers can be used to monitor the production process to ensure that the numbers of chocolate chips stays below P_1.
Explanation / Answer
P1= -2.32635*2.1+24.4= 19.5
P99= 2.32636*2.1+24.4= 29.3
Option A is correct for last part
