Question: Consider taking a random sample of size 2 (rather than of size 3) from the knee replacement population of Example 5.1.3. (a) How many possible

Consider taking a random sample of size 2 (rather than of size 3) from the knee replacement population of Example 5.1.3.
(a) How many possible samples of size n = 2 are then and what are those possible samples?
(b) What is the sampling of the total surgery costs for samples of size n = 2? That is, make a table similar to Table 5.1.2 but for n = 2 rather than n = 3.
(c) What is the probability that the total surgery costs will exceed $75,000?
