Stern 13.4 Problem Description In April 1992, the minimum wage in New Jersey went from $4.25 to $5.05 an hour. The data are in the file MinWage.sav, and came from randomly selected fast food restaurants about one month before and eight months after the wage increase took effect. We performed the following analyses: 1. Selected just the stores from New Jersey (using the Select Cases command) 2. Determined if the wage change had an effect on the number of full-time employees, part-time employees, and managers/assistant managers. 3. Determined if the wage change had an effect on the price of a medium soda or the price of a small fry. Report the results of the analyses in proper APA format, including effect sizes for all analyses. Assume a non-directional test in all cases, and use a .05 alpha level.
