1. Here are the diameters of the tires of three different vehicles. Calculate their circumferences, rounding to the nearest tenth. Car tire 17” in diameter: 53.4 in
Bike tire 26” in diameter: 81.7 in
School Bus 19.5” in diameter: 61.3 in

2. Determine the number of full rotations the tires of each of the vehicles will complete in 10,000 miles, rounding to the nearest tenth.
Car tire 17” in diameter:
Bike tire 26” in diameter:
School Bus 19.5” in diameter:

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
