A researcher is trying to estimate the percentage of adults who exercise daily. Using a simple random sample, the researcher found a mean of 23% of adults, but he has a margin of error of 10%.
--- What is the range that includes the actual mean percentage of adults who exercise daily?
--- What could he do to lower the margin of error?

its 4 because 2 times 2 is 4, if you double the number two you get four

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
