Question
Exercise 5.21 METHODS AND APPLICATIONS
Suppose that x is a binomial random variable with n = 5, p = 0.12, and q = .88.
For each value of x, calculate p(x). (Round final answers to 4 decimal places.)
Find P(x 3). (Do not round intermediate calculations. Round final answer to 4 decimal places.)
Find P(x < 3). (Do not round intermediate calculations. Round final answer to 4 decimal places.)
Find P(x 4). (Do not round intermediate calculations. Round final answer to 4 decimal places.)
Find P(x > 2). (Do not round intermediate calculations. Round final answer to 4 decimal places.)
Calculate the interval [x ± 2x]. Use the probabilities of part b to find the probability that x will be in this interval. Hint: When calculating probability, round up the lower interval to next whole number and round down the upper interval to previous whole number. (Round your answers to 4 decimal places. A negative sign should be used instead of parentheses.)
