Warm Up:
Elly and Ramon are both conducting surveys to compare the average
numbers of hours per month that men and women spend shopping. Elly
plans to take many samples of size 10 from both populations and
compare the distributions of both the medians and the means. Ramon
will do the same, but will use a sample size of 100.
Whose results will probably produce more reliable inferences? Explain.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
