Telemarketers use a predictive dialing system to decide whether a person actually answers a call (as opposed to an answering machine). If so, the call is routed to a telemarketer. If no telemarketer is free, the software must automatically hang up the phone within two seconds, to comply with FAA regulations against tying up the line. The Touchstar company says that its new system is smart enough to hang up on no more than 2 percent of the answered calls. Write the hypotheses for a right-tailed test, using Touchstar’s claim about the proportion as the null hypothesis. (See The New York Times, Nov. 15, 2007, p. C12.)
