The Thompson Tire Company did research in Alabama regarding the miles their commercial truck tires would travel before they no longer met the Federal Highway Department tread depth requirements. The results of their study are in the file “Thompson Data Spring 2019” and show the mileage in 1,000 miles. Calculate the mean, median and mode of the data. Develop a box plot. Are there any outliers? Do the amounts follow a symmetric distribution or are they skewed? Justify your answer....

West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the time above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to...
