Answer 8

8) The likelihood that a pet owner owns birds is p = 0.40. A sample ofn = 10 pet owners was taken. (a) Using the Binomial Probability Computing Formula, calculate the likelihood that exactly 3 ofthe ten pet owners will be bird owners. Show all work. Write your answer using correct probability notation. (b) Using the Binomial Probability Tables attached to the end of this test, determine the likelihood that at most 3 of the ten people sampled will own birds. Write your answer using correct probability notation. (c) Using the Binomial Probability Tables attached to the end of this test, determine the likelihood that between 2 and 5 (inclusive) of the ten people sampled will own birds. Write your answer using correct probability notation. ((1) Find the mean and standard deviation of this Binomial random variable using the appropriate shortcut formulas for a binomial random variable
