Suppose that a newspaper article claims that 80% of adults currently use online banking services. You wonder if the proportion of adults who use online banking services in your community, p, is actually this large. You take a sample of 100 adults and 70 tell you they use online banking. a. If the newspaper article is accurate, find the probability that 70 or fewer of your sample would use on- line banking. b. Based on your computation, is there sufficient evidence to suggest that less than 80% of your community use online banking services? Explain.
