Objective: To gain experience working with memory-mapped I/O. Instructions 1. Write and test a function to draw a box on the bitmap display. The box should be roughly in the center of the screen. Draw the box one pixel at a time. Use 4 loops, one for the top, one for the right side, one for the bottom, one for the left side. Each loop writes 7 pixels per side. To make debugging easier, make the box a solid color first, then go on to step
2. Make sure that your code uses these settings: 2. Modify the draw box function to have the marquee effect by drawing each pixel in a color from an array of colors. You can use colors similar to the following:
3. Slow the marqee appearance down by adding a pause function between pixel writes, using syscall 32. Make the delay 5 ms.
4. Add keyboard functionality. You can see similar code in the bitmap sample program 2 in the GitHub. The w, a, s, and d keys should move the box up, left, right, or down one pixel. The space key should terminate 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.
