Suppose that the number of years a certain species of bird lives follows an Exponential distribution with a decay parameter of M=0.175 Round any probabilities to three decimals, then round final answers to one decimal if needed. a. Out of a random sample of 63 birds, how many would you expect to live longer than 7 years? b. What is the percentile of a bird that lives 8 years? c. Find the cutoff age for the oldest 14 percent of birds of this species. d. What is the life expectancy (in years) of this species of bird?
