Suppose that you want to estimate the relationship betweenβ people's weight β(Wβ) and the number of times they eat out in a month β(EOβ):
β,
where is the intercept of the population regressionβ line; is the slope of the population regressionβ line; is the errorβ term; and the subscript i runs overβ observations, iβ1, ...β , n.
Forβ this, you collect data from a random sample of people 250. After analyzing theβ data, you determine that the covariance betweenβ people's weight and the number of times they eat out in a month is 4.85 and the variance of the number of times people eat out in a month is 3.59. You also find that the mean weight of people in the sample is 62.36 kg and the mean number of times people eat out in a month is 2.46 .
The OLS estimator of the slope is
