Shown below are data on the total sales generated by the seafood industry and the corresponding jobs supported by the seafood industry in the top 15 states by seafood sales. The data are published by the National Marine Fisheries Service of the National Oceanic and Atmospheric Administration of the U.S. Department of Commerce. Develop a simple regression model to predict the number of jobs supported by the seafood industry for a state from the total sales generated by the seafood industry of a state. Construct a confidence interval for the average y value for sales of$3,000 (million).Use the t statistic to test to determine whether the slope is significantly different from zero using α=.05.
