Checking In Fewer Americans are really getting away while on vacation. In fact, among small business owners, more than half (51%) say they check in with the office at least once a day while on vacation; only 27% say they cut the cord completely.7 If 20 small business owners are randomly selected, and we assume that exactly half check in with the office at least once a day, then n = 20 and p = .5. Find the following probabilities.
a. Exactly 16 say that they check in with the office at least once a day while on vacation.
b. Between 15 and 18 (inclusive) say they check in with the office at least once a day while on vacation.
c. Five or fewer say that they check in with the office at least once a day while on vacation. Would this be an unlikely occurrence?
