Table 3.4 on page 174 gives the number of points for all 24 players on the Ottawa Senators NHL hockey team, also available in the dataset Ottawa Senators.

Table 3.4

(a) Use StatKey, other technology, or a random number table to select a random sample of 5 of the 24 Points values. Indicate which values you€™ve selected and compute the sample mean.
(b) Repeat part (a) by taking a second sample and calculating the mean.
(c) Find the mean for the entire population of these 24 players. Use correct notation for your answer. Comment on the accuracy of using the sample means found in parts (a) and (b) to estimate the population mean.
(d) Give a rough sketch of the sampling distribution if we calculate many sample means taking samples of size n = 5 from this population of Points values. What shape will it have and where will it be centered?
