1. consider a large population which has population mean µ, and population variance σ2. we take a sample of size n = 3 from this population, thinking of the samples as realizations of the rvs x1, x2, and x3, where the xi can be considered iid. we are interested in estimating µ. (a) consider the estimator ˆµ1 = x1 + x2− x3. is this estimator unbiased for µ? explain your answer.

step-by-step explanation:

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
