The mean price for used cars is $10,145 . A manager of a Kansas City used car dealership reviewed a sample of 50 recent used car sales at the dealership in an attempt to determine whether the population mean price for used cars at this particular dealership differed from the national mean. The prices for the sample of 50 cars are shown in the table below. 11,359 10,829 10,380 11,454 13,176 8,397 12,559 6,594 11,558 12,653 10,750 6,319 12,018 11,176 11,644 8,221 12,408 11,007 10,063 8,583 12,736 8,142 12,681 6,435 6,297 6,906 11,064 12,476 12,103 6,240 6,668 7,427 13,041 11,237 7,131 10,306 8,228 10,245 7,683 9,775 11,166 6,524 6,487 8,317 11,815 9,836 10,249 11,173 7,156 8,307 b.
