An advertising firm, interested in determining how much to emphasize on television advertising in a certain region of three major divisions referred to as Town A,Industrial zone and Rural. The firm decided to conduct a sample survey to estimate the average number of hours each week that a house hold within the region watchtelevision and proportion of households viewing show W. There are 310, 124 and 186 households in town A, industrial zone and rural area; respectively. Assume that astratified random sampling method is suitable to obtain the observations and that the advertising firm has enough resource to interview 80 to 85 households. The Tablebelow summarizes the results of the survey.SampleSizeSampleMeanNumberVarianceviewing show WRegionTown40343532Industrial Zone16252334Rural area24198812a.
