Gestation Times and Longevity Thetable below, a subset of the data given in Exercise3.33, shows the gestation time in days and the averagelongevity in years for a variety of mammals in captivity.4Gestation Avg LongevityAnimal (days) (yrs)Baboon 187 20Bear (black) 219 18Bison 285 15Cat (domestic) 63 12Elk 250 15Fox (red) 52 7Goat (domestic) 151 8Gorilla 258 20Horse 330 20Monkey (rhesus) 166 15Mouse (meadow) 21 3Pig (domestic) 112 10Puma 90 12Sheep (domestic) 154 12Wolf (maned) 63 5a. If you want to estimate the average longevity of ananimal based on its gestation time, which variableis the response variable and which is the independentpredictor variable?b. Assume that there is a linear relationship betweengestation time and longevity. Calculate the leastsquaresregression line describing longevity as alinear function of gestation time.c. Plot the data points and the regression line. Does itappear that the line fits the data?d. Use the appropriate statistical tests and measures toexplain the usefulness of the regression model forpredicting longevity.
