1. The distribution of scores on your statistics test is skewed. What does that indicate about the difficulty of the test? (Hint: sketch a graph to help you visualize the distribution) 2. The lower boundaries for the number of tatoos among prison inmates are 1, 4, 7, 10, 13, and 16. List the value for each upper boundary in this distribution. 3. The frequency of alcohol related arrests during a single season at a sporting arena ranged from 0 to 29 arrests per game. What is the interval width if you choose to create a frequency distribution table with six intervals? 4. Sophia scored at the 10th percentile (P10) on exam 1. She claims that this means she outperformed 90% of the class. Is she correct? Explain. 5. Organize the ratio level scores below into a simple frequency distribution table. Include columns for the frequency, relative frequency, percent, cumulative frequency, and cumulative percent. 49 52 47 52 52 47 49 47 50 51 50 49 50 50 50 53 51 49 - make the appropriate graph for this data - make a stem and leaf plot of this data
