Suppose we are writing a c++ program for the sales department of a small company. the department has 4 sales person and is selling 5 products. the program will allow the input of each sale made (sales person, product, sales amount). the program will also allow a user to see the sales made by a particular sales person or the sales on a particular product. requirement of the program: 1. using a 2-d array as a data structure for storing the sales information2. containing a menu that allows a user to1. enter a sale2. check the sales made by a sales person3. check the sales on a product4. exit the program

Explain the circumstances for which the interquartile range is the preferred measure of dispersion. what is an advantage that the standard deviation has over the interquartile range? choose the correct answer below. a. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it increases as the dispersion of the data increases. b. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. c. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it is resistant to extreme values. d. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it is resistant to extreme values. e. the interquartile range is preferred when the data are skewed or have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. f. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it increases as the dispersion of the data increases.
