In the data set of weights of hummingbirds (in grams) randomly selected from a population, below, what proportion of the observations fall within 1, 2, and 3 standard deviations of each other, and do these figures indicate that the sample may have come from a normally distributed population? A.) 69%, 92%, 100%; yes
B.) 69%, 92%, 100%; no
C.) 50%, 89%, 99%; yes
D.) 50%, 89%, 99%; no
E.) Can't be determined

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
