V. USE THE INFORMATION BELOW TO ANSWER PROBLEMS 16-18 Suppose that long time data shows that patrons of coffee houses on average get coffee at 13.23 hours with a standard deviation of 3.46 hours (hours as measured on a 24-hour clock). The data is assumed to be approximately Normally distributed. What should the opening and closing times be for a coffee house that wishes to serve 99% of all patrons? 16. Pick the equation that is most appropriate to answer the question above. a) = b) = c) = d) () = e) None of the above 17. Select the most appropriate item that pertains to the problem. a) z = 1.96 b) z = 2.33 c) z = 1.53 d) z = 2.58 e) None of the above 18. What would the opening/closing times be, when rounded to the nearest hour (using the 24- hour clock)? a) Open 5; Close 21 hours b) Open 4; Close 22 hours c) Open 8; Close 19 hours d) Open 6; Close 20 hours e) None of the above
