Here are the summary statistics for the weekly payroll of a small company: iowest salary $300, mean salary $900, median = $800, range = $1200, IQR = $800, first quartile = $350, standard deviation = $350. a) Do you think the distribution of salaries is symmetric, skewed to the left, or skewed to the right? Explain why. O A. The distribution is skewed to the right because the mean is greater than the median. O B. The distribution is symmetric because the mean is greater than the median. O C. The distribution is skewed to the left because the mean is greater than the median. O D. There is not enough information to estimate the shape of the distribution. b) Between what two values are the middle 50% of the salaries found? The middle 50% of the salaries are found between $ and $. c) Suppose business has been good and the company gives each employee a $100 raise. Tell the new value of each of the summary statistics. After everyone receives a $100 raise, the new lowest salary is $. After everyone receives a $100 raise, the new mean salan in s
