A corporation wishes to obtain information on the effectiveness of a businessmachine. Several division heads will be interviewed by telephone and asked torate the equipment on a numerical scale. The divisions are in North America,Europe, and Asia. Hence, stratified sampling is used. The costs are larger forinterviewing division heads located outside North America. Table Q5(c) givesthe costs per interview, approximate variances of the ratings, and N that havebeen established. Suppose the corporation wish to take a stratified randomsample of 50 division heads among the populations established.Table Q5(c)Population, NStratumLocationCostsVariance, o?1North America1129.2.25EuropeAsia68253.24339363.24(i)Calculate the random sample by using the proportional allocation tochoose 50 division heads among the populations established.(ii)Calculate the random sample by using the optimal allocation to choose50 division heads among the populations established.

The accompanying table gives amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different states? Given that the amounts of arsenic in the samples from Texas have the highest mean, can we conclude that brown rice from Texas poses the greatest health problem? Click the icon to view the data.
