Question

A local pediatrician office is interested in the "˜no-show" appointment count for each of the 4 pediatricians. "˜No-show" appointments represent lost revenues because the physician will be idle when patients do not show for their scheduled appointments. Using the data in the table below and an alpha of .10, what is the appropriate decision?

Physician APhysician BPhysician CPhysician D
week 18467
week 27346
week 38254
week 48679
week 542510
a) Reject the null hypothesis and conclude at least one physician differs in the no-show rates.
b) Reject the null hypothesis and conclude the no show rates differ by day of week
c) Fail to reject the null hypothesis and conclude there is not enough evidence to demonstrate the no show rate between physician is equal
d) Fail to reject the null hypothesis and conclude there is not enough evidence to show the no show rate between days of the week is equal
e) Reject the null hypothesis and conclude the no show rates are dependent upon both day of week and physician.
