In crash tests at five miles per hour, the mean bumper repair cost for 12 small cars is 572 dollars with a standard deviation of 178 dollars. In similar test of 25 midsize cars, the mean bumper repair cost is 700 dollars with a standard deviation of 252 dollars. Conduct a hypothesis test based on this sample data, with o = 1%. Answer the question, is the mean bumper repair cost less for small cars than it is for midsize cars? (a) State the hypotheses: Ho: The population mean vo bumper repair cost for small cars is equal to V the population mean wa bumper repair cost for midsize cars. Symbols: P Hi - OMO #1 - 12 4; HE -EH Of 0 Ha: The population mean vv of bumper repair cost for small cars is less than V V the | population mean vo bumper repair cost for midsize cars. Symbols: P # #1 - #2 HO A -, HE -EO HOVVO 0 (b) The correct symbol for the mean of the sampling distribution is: On - 12 Op Op1 - P2 Ou OHn - 12 Op OHI Opp Or (c) The value for the mean of the sampling distribution is: |0 (d) Choose the correct distribution: O Chi-Square Distribution OT-Distribution O Normal DistributionWhy? We are provided with o for both populations. The size of n1
