Consider the following data for a dependent variable y and two independent variables,
x1
and
x2.
x1 |
x2 |
y |
---|---|---|
30 | 12 | 94 |
47 | 10 | 108 |
25 | 17 | 112 |
51 | 16 | 178 |
40 | 5 | 94 |
51 | 19 | 175 |
74 | 7 | 170 |
36 | 12 | 117 |
59 | 13 | 142 |
76 | 16 | 211 |
(a)
Develop an estimated regression equation relating y to
x1.
(Round your numerical values to one decimal place.)ŷ =
Predict y if
x1 = 43.
(Round your answer to one decimal place.)
(b)
Develop an estimated regression equation relating y to
x2.
(Round your numerical values to one decimal place.)ŷ =
Predict y if
x2 = 19.
(Round your answer to one decimal place.)
(c)
Develop an estimated regression equation relating y to
x1 and x2.
(Round your numerical values to one decimal place.)ŷ =
Predict y if
x1 = 43
and
x2 = 19.
(Round your answer to one decimal place.)
