You compare the height and weight of 5 adult women. You get the following results:

height     weight

60            121

67            143

62            131

70            153

66            138

Now let's assume you wanted to predict weights from heights. In other words, now let's use the same data from problem (1) and do a regression instead.

(a) Calculate b0 and b 1

(b) Carefully draw your least square regression line on the plot you made in 1(a). (Don't just “sketch”, be a little careful)
