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.

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
