Pls I need details
Suppose the mean price for used cars is $10,191. 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 file named UsedCars. 12,400 10,400 12,100 10,000 11,000 8,895 7,675 9,975 9,895 11,250 8,795 12,500 10,000 7,500 8,000 10,440 10,200 9,000 7,680 9,400 9,440 9,340 8,970 9,500 10,050 10,130 Ho: > 10,191 Ha: ≤ 10,191 O Ho: < 10,191 H:μ ≥ 10,191 O Ho: ≤ 10,191 H> 10,191 10,730 7,350 O Ho: H = 10,191 H: μ # 10,191 ype 10,300 9,740 10,150 9,200 9,395 11,000 10,640 12,240 11,970 11,400 8,500 (b) What is the test statistic?
