Question
QUESTION ONE The Department of health and social services in a certain district in Ghana reimburses nurses for services provided. One purpose of a recent study was to investigate the effects of ownership (Private Party, Non-Profit Organization and Government) or certification (skilled nursing facility, intermediate care facility or both) on costs. Four costs computed on per patient day basis and measured in hours per patient day were selected for analysis: x,= Cost of nursing labour, x,=Cost of dietary labour, x,= Cost of plant operation and maintainance labour and x,= Cost of housekeeping and laundry labour. A total of n=516 observations on each of the p=4 cost variables were initially separated according to ownership. Summary statistics for each of the g=3 groups are given below: Group: 4 = (Private), 1,-2(Non Profit) and 1,=3 (Government). With sample sizes: m-271, n. =138 and n, =107.
