In a survey from a certain year, the range of annual salaries reported was from $73,187 to $336,550. But do CEO salaries differ across the two most populous states in the United States? Consider the salaries from that year for CEOs who work for companies headquartered in California and Texas as provided in the following table. CEO Salaries (in $1,000s) California Texas $319 $92 $119 $214 $140 $159 $181 $246 $317 $198 $261 $305 $123 $185 $132 $202 $273 $90 $304 $179 $226 $208 $194 $109 Use α = 0.05 and test to determine whether the distribution of CEO salaries is the same for California and Texas.
