A researcher wants to know if the gestation period (in days) of an animal can be used to predict life expectancy (in years). Data are recorded for 10 different animals. The scatterplot and regression line are given below. Life expectancy 13- 12- 11- 10 16 8 7- 6 50 100 Gestation period ŷ 7.874 +0.026x 150 Select the correct interpretation of the slope of this regression line. If the life expectancy increases 1 year, the gestation period will increase 0.026 days, on average. If the gestation period increases 1 day, the life expectancy will increase 0.026 years, on average. If the life expectancy increases 1 year, the gestation period will increase 0.026 days. If the gestation period increases 1 day, the life expectancy will increase 0.026 years. If the gestation period increases 0.026 days, the life expectancy will increase 1 year, on average.
