A researcher would like to know if the gestation period of an animal can be used to predict the life expectancy. She collects the following data. Animal Gestation (incubation) Period (days) Life Expectancy (years) Cat 63 11 Chicken 22 7.5 Dog 63 11 Duck 28 10 Lion 108 10 Parakeet 18 8 Pig 115 10 Rabbit 31 7 Squirrel 44 9 Goat 151 12 Humans 268 76.5 (b) The type of relation that appears to exist between gestation period and life expectancy based upon the the linear correlation coefficient is ( positive, negative or no relation). positive. (b1) This means that the Blank 3 the gestation period, the longer the life expectancy of an animal. (b2) Or this means that the shorter the gestation period, the Blank 4 the life expectancy of an animal.
