Suppose we want to estimate the proportion of families in a town, which have two or more children. A random sample of 144 families shows that 48 families have two or more children. Setup a 95 per cent confidence interval estimate of the population proportion of families having two or more children.

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
