Suppose we have a data set containing n=100 data points with the following descriptive statistics: mean = 80, and standard deviation = 18. We believe that this data sample comes from a normal distribution. Which of the following choices would you use for forecasting or predicting future demand values? Mean= 80 and standard deviation= 18.
Mean= 80 and standard deviation= 19.8. Mean= 81.8 and standard deviation= 18.
Mean=88 and standard deviation= 19.8.
Mean= 81.8 and standard deviation=19.8.https://www.coursehero.com/file/63883624/operations-analytics-week-1-newsvendor-and-forecasting-quiz-1docx/This study resource was
