- Provide an appropriate chart for the give dataI am having an issue completing this probelm in R. Can't figure out how to divide autodths./14 in R. Here is the problem: The state of Arizona records the number of automobile two years ago in each of the state’s 14 counties: 30, 15, 183, 9, 7, 39, 28, 30, 76, 13, 21, 18, 323, 3 (a) Using R, enter these data into a variable called autodths. autodths. = c(30, 15, 183, 9, 7, 39, 28, 30, 76, 13, 21, 18, 323, 3) (b) What is the mean number of deaths per county? What is the median number of deaths per county? Can you explain why these two measures are so different? > autodths. = c(30, 15, 183, 9, 7, 39, 28, 30, 76, 13, 21, 18, 323, 3) > mean ( ~ autodths.) [1] 56.78571 (i need in code to divide this by 14, not sure how) > median ( ~ autodths.) [1] 24.5 The mean value is the average number of deaths, very different than the median number of deaths which is simply the middle number of deaths when the numbers are ordered sequentially. (c) What is the range of the numbers of deaths?…The data was collected on the time spent for preparation of exams by a class of statistics students before one week of examination data.
