The table shows gestation period (in days) and life expectancy (in years) in several animals. Animal Gestation Life Expectancy bear 210 22 cat 63 11 dog 63 13.3 donkey 365 40 duck 28 10 elephant 624 60 goat 151 16 horse 336 28 pig 115 10 rabbit 31 7 sheep 151 12 squirrel 44 9b. Based y height and BMI? Explain. Gestation and life expectancy 10.5.22 The data in the file GestationLife Expectancy gives the ges- tation period (in days) and the life expectancy (in years) for a sample of mammals. We will consider this sample to be representative of all mammals for these two variables. Consider conducting an analysis to test whether the sample data provide strong evidence of an associa- tion between gestation period and life expectancy. a. What is the value of the slope of the regression line and what does it mean in terms of gestation period and life expectancy? b. State the appropriate null and alternative hypotheses in terms of the population slope. c. Use a theory-based approach to find a p-value. Do you have strong evidence of an association between the two variables? d. Remember that a Type II error is not rejecting a false null hypoth- esis (or a missed opportunity). Do you think you made a Type II error for this exercise? Why or why not
