It provides numerical data on the responses, including counts for each category. Additionally, it poses questions regarding the calculation of the population mean and variance.

1. Population Characteristics/Parameters - Example Of these ticket holders, - 3,000 responded
"Definitely Yes" (which is coded as +2) - 2,000 responded "Prefer Yes" (coded as +1) - 2,000
responded "Don't Care" (coded as 0) - 1,000 responded "Prefer No" (coded as -1) - 2,000
responded "Definitely No" (coded as -2) What is the population mean () ? What is the population
variance (2) ? =NVi2=N(Vi)2
