The data shown below are the initial weights and gains in weight (in grams) of female rats on a high protein diet from 24 to 84 days of age. The point of interest in these data is whether the gain in weight is related to (dependent on) the initial weight. If so, then feeding experiments on female rats can be made more precise by adjusting for differences in initial weights of the rats. Statistically test this with a regression analysis.

The following data give the yearly inflation rate and money supply growthrate (both measured in percentage) for 51 countries. A simple regression of Infla-tion on Growth yields the following information from RegressIt output: (a) What is the linear relationship implied by these data? (b) For a country with an 6% money supply growth, what would be theexpected inflation? (This means Growth= 6 as it is measured in percentage.) (c) A simplistic monetarist claims that a 1% increase in the money supplygrowth rate would result in a corresponding 1% increase in inflation. In otherwords, for the relationship of Inflation = β0 + β1Growth, the null hypothesis isβ1 = 1. Do the regression results support this null hypothesis?
