In crash tests at 5 miles per hour of 23 randomly selected midsize cars, the mean bumper repair cost is $741 with a standard deviation of $205. In similar tests of 14 randomly selected small cars the mean bumper repair cost is $473 with a standarc deviation of $190. Assume the populations of repair costs for small and midsize cars are approximately normally distributed. 1. Estimate the difference between mean repair costs for midsize and small cars using 90% level...

PROBLEM 8/ Question 12 (2 points): Based on data from High-way Loss Data Institute, in crash tests of 22 randomly selected Honda Odyssey minivans the average collision repair cost is found to be $1,786 with the standard deviation of $835. Calculate a 90% confidence interval for the average repair cost in all Honda Odyssey minivans collisions. (Round your boundaries to 2 places after the decimal point). a) (1,493.15, 2,078.85) $ b) (1,437.08, 2,134.92) $ c) (1,327.41, 2,244.59) $ d) None...

An institute published data on repair costs for cars involved in different types of accidents. In one study, seven different models of mini- and micro-cars were driven at 6 mph straight into a fixed barrier. The following table gives the cost of repairing damage to the bumper for each of the seven models. Model Repair Cost Smart Fortwo $1,480 Chevrolet Aveo $1,079 Mini Cooper $2,295 Toyota Yaris $1,683 Honda Fit $1,122 Hyundai Accent $3,475 Kia Rio $3,708 (a) Compute the...

An automotive engineer wants to estimate the cost of repairing a car that experiences a 40 kph head-on collision. He tests 24 crashed cars in a crash-test experiment, and the average repair is $11,000. The standard deviation of the 24-car sample is 2.9 THOUSAND dollars. Determine the margin of error for a 95% Confidence interval for the true mean repair cost. (NB WE ARE LOOKING FOR A 4-DIGIT WHOLE DOLLAR AMOUNT.)
