The November 24, 2001, issue of The Economist published economic data for 15
industrialized nations. Included were the percent changes in gross domestic product (GDP),
industrial production (IP), consumer prices (CP), and producer prices (PP) from Fall 2000
to Fall 2001, and the unemployment rate in Fall 2001 (UNEMP). An economist wants to
construct a model to predict GDP from the other variables. A fit of the model
GDP = , + P,IP + 0,UNEMP + f,CP + P,PP + €
yields the following output:
The regression equation is
GDP = 1.19 + 0.17 IP + 0.18 UNEMP + 0.18 CP – 0.18 PP

- When wildebeest are more abundant, they graze the grass more heavily, so there are fewer fires and moretrees grow. Lions feed more successfully when there are more trees, so the lion population increases. Thedata on one part of this cycle, wildebeest abundance (in thousands of animals) and the percent of the grassarea that burned in the same year are on the spreadsheet. To what extent do these data support the claim that more wildebeest reduce the percent of grasslands that burn? How rapidly does burned area decrease as the number of wildebeest increases? To answer these questions, create a scatterplot and add the regression line. Describe the scatterplot. Interpret the slope and intercept in context of the problem. Does the intercept explanation make sense in the real world? Find the correlation coefficient and coefficient of determination. What do they tell us about the relationship between number of wildebeest and percent of grassland burned?

What might be the effect of early exposure to antibiotics on children's development? One study followed 11,532 full-term babies all born in the county of Avon, United Kingdom, during 1991 and 1992. Exposures to antibiotics during infancy were recorded, along with measures of body mass at regular intervals over several years. The researchers found that antibiotic exposure during the first six months of life was associated with increased body mass later in childhood.arrow_forwardSauces_Data Store Sales Sauce type 1 169 Sauce1 2 242 Sauce1 3 175 Sauce1 4 253 Sauce1 5 236 Sauce1 6 158 Sauce1 7 231 Sauce1 8 205 Sauce1 9 169 Sauce1 10 178 Sauce1 11 200 Sauce1 12 200 Sauce1 13 229 Sauce1 14 230 Sauce1 15 193 Sauce1 16 234 Sauce1 17 218 Sauce1 18 211 Sauce1 19 218 Sauce1 20 152 Sauce1 21 223 Sauce1 22 174 Sauce1 23 225 Sauce1 24 194 Sauce1 25 197 Sauce1 26 223 Sauce1 27 150 Sauce1 28 190 Sauce1 29 196 Sauce1 30 202 Sauce1 31 197 Sauce1 32 220 Sauce1 33 245 Sauce1 34 196 Sauce1 35 222 Sauce1 36 202 Sauce1 37 289 Sauce1 38 229 Sauce1 39 193 Sauce1 40 216 Sauce1 41 160 Sauce2 42 209 Sauce2 43 175 Sauce2 44 172 Sauce2 45 206 Sauce2 46 188 Sauce2 47 185 Sauce2 48 171 Sauce2 49 175 Sauce2 50 207 Sauce2 51 209 Sauce2 52 207 Sauce2 53 181 Sauce2 54 222 Sauce2 55 197 Sauce2 56 166 Sauce2 57 189 Sauce2 58 178 Sauce2 59 167 Sauce2 60 210 Sauce2 61 228…arrow_forward
