. Consider the following data:
N = 10000 (i.e. ten thousand)
SS =15
M = 20
m = 21
6a. Treat these data as if they came from a population and calculate the appropriate z-score (remember to round to four decimal places throughout your calculations).
6b. Treat these data as if they came from a sample and calculate the appropriate t-score (remember to round to four decimal places throughout your calculations).
