1. (65 pts) The following data are the rates of oxygen consumption of birds, measured at differentenvironmental temperatures:T (C) -18 -15 -10 5 0 5 10 19

O2 consumption(ml/g/hr) 5.2 4.7 4.5 3.6 3.4 3.1 2.7 1.8

a) Calculate the intercept, a, and slope, b, for the regression of oxygen consumption rate ontemperature.

b) Test the null hypothesis H0: = 0, by analysis of variance.c) Test the null hypothesis H0: = 0, by t-test.d) Calculate the standard error of the estimated slope, as well as 95% confidence interval.e) Calculate the coefficient of determination of the regression.
