    It is hypothesized that the number of bottles of an imported premium beer sold in city restaurants depends linearly on the average cost of meals in these restaurants. The following results were obtained for a sample of n = 20 restaurants of approximately equal size:
    x = 30
    y = 18.8
    Var(x) = 412
    Cov(x,y) = 212

    y = Number of bottles of important premium beer sold
    x = Average cost, in dollars, of a meal

    Please show how to calculate for regression coefficients.
