A study estimated the number of to NOx poilution produced from the vehicles over the 7-year period. The researchers computed the estimate for each of 27 which in miles) d for the number of deaths are shown in the table below Suppose the media have requested that the statistic that best of estimated deaths a to NOx polution produced by the manufacturer's illegal vehidles. This statistic will be used to Variable N Mean StDev Minimum Q1 Median 03 Maximum Deaths 29 153.8 237.6 2.3 27.6 65.5 201.9 1003.3 A. They would report the mean, because it is the highest measure of central tendency B. They would report the c. They would report the median, because it is the lowest measure of central tendency Xo. They would report the maximum, because it appears honest, implying there is nothing to hide O E. They would report the standard deviation, because it shows how much variability the data have; implying the data set is unreliable b. If a member of an environmental watch group would lke to incite the media to publicize the emissions scandal, which statistic would they choose to report and why? Choose the correct answer btause is the lowest measure in the report. below O A They would report the mean, because it is the highest measure of central tendency. B. They would report the minimum, because it is the lowest measure in the report. O C. They would report the maximum, because it is the greatest value that can be used. O D. They would report the median, because it is the highest measure of central tendency O E. They would report the standard deviation, because it shows how litle variability the data have; implying the data set is reliable.

Explanation / Answer

By seeing the minimum, maximum and standard deviation we conclude that has too many outliers which will influence the mean value.

So, correct statistic will be Median.
