Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively.

A meat-processing company in Alberta produces and markets a package of eight small sausage sandwiches. The product is nationally distributed, and the company is interested in knowing the average retail price charged for this item in stores across the country. The company cannot justify a national census to generate this information. Based on the company information system’s list of all retailers that carry the product, a company analyst contacts 36 of these retailers and ascertains the selling prices for the product. Use the following price data and a population standard deviation of 0.113 to determine a point estimate for the national retail price of the product. Construct a 98% confidence interval to estimate this price. $2.23 $2.11 $2.12 $2.20 $2.17 $2.10 2.16 2.31 1.98 2.17 2.14 1.82 2.12 2.07 2.17 2.30 2.29 2.19 2.01 2.24 2.18 2.18 2.32 2.02 1.99 1.87 2.09 2.22 2.15 2.19 2.23 2.10 2.08 2.05 2.16 2.26
