The data below represent the repair cost for a low impact collision and a simple random sample of mini and micro vehicles $3148 1758 1071 3345 743 2057 663 2637 773 1370 assume a probability normal probability plot suggest the data could come from a population that is normally distributed. A box plot does not show outliers. Does the sample evidence suggest the cost of repairs to exceed $12,000? a) what type of test should we use? b) write the hypothesis and specified the type of test (tailing). Use the appropriate notation for the hypothesis. c) calculate (formula/values) The test statistic and the associated P value range from the table d) State the decision of the test e) Express your conclusion concisely using statistically appropriate language applied to repair costs
