Back Pain Six in 10 adults say lower back pain substantially limits their athletic activities.3 A random sample of n = 8 adults were asked if lower back pain was a limiting factor in their athletic activities. The printout below shows the cumulative and individual probabilities for a binomial random variable with n = 8 and p = .6.

a. Use the binomial formula to find the probability that all eight indicate that lower back pain was a limiting factor in their athletic activities.

b. Confirm the results of part a using the printout.

c. What is the probability that at most seven individuals give lower back pain as a limiting factor in their athletic activities?
