You measure the length of 11 bullfrogs (Lithobates (=Rana) catesbeiana), and then measure how for each
frog can jump. You get the following results (size in mm, jump distance in cm).
Size 155 127 136 135 158 145 136 172 158 162 162
Distance 71.0 70.0 100.0 120.0 103.3 116.0 109.2 105.0 112.5 114.0 122.9
You find the following results:
SSx = 2,094.55 SSy = 3,218.99 SScp = 731.36 n = 11 ¯y = 103.99 ¯x = 149.64
SSresid = 2,963.61
a) Give the equation of the least squares line.
b) Give both the test statistic and the table value. Make sure you give H0, H1, α, etc. and state
your conclusion.
c) Make a scatterplot of these data and fit the least squares line.
d) Make a residual plot of these data and comment on it.
e) Calculate R
