The following table shows the average life expectancy, in years, of a child born in the US in the given year. t(years since 2000) Life expectancy (in years) 76.6 2. 76.9 4. 77.5 6. 77.7 78.0 10 78.5 12 78.7 14 78.8 a) Use Desmos.com to find the equation of the regression line (round to 3 decimal places). b) Explain in practical terms the meaning of the slope of the regression line. How the age of the children is changing per year How life expectance changes with age OHow much life expectancy changes per year of the person's date of birth How quickly time is going by ) Based on the trend of the regression line, what do you predict as the life expectancy of a child born in 2020, to the nearest one decimal place.
