Did I do the top 4 questions right? How do I determine if it is skewed or symmetric?

This Question: 1 pt 23 of 26 (11 complete) This Test: 26 pts possible Violent crimes include rape, robbery, assault, and homicide. The following is a summary of the violent-crime rate (violent crimes per 100,000 population) for all states of a country in a certain year, Complete parts (a) through (d). Q1 = 271 8, Q2 =387 9, Q3 = 529.1 B. The middle 50% of all observations have a range of 257.3 crimes per 100,000 population. O C. All observations have a range of 257.3 crimes per 100,000 population. O D. The middle 50% of all observations have a range of 116.1 crimes per 100,000 population (c) The violent-crime rate in a certain state of the country in that year was 1,467, Would this be an outlier? The lower fence is -114.15 crimes per 100,000 population. The upper fence is 915 05 crimes per 100,000 population. (Round to two decimal places as needed.) The violent-crime rate in a certain state of the country in that year was 1,467. Would this be an outlier? O A. Yes, because it is greater than the upper fence O B. No, because it is greater than the upper fence. O C. No, because it is less than the upper fence. O D. Yes, because it is less than the upper fence. (d) Do you believe that the distribution of violent-crime rates is skewed or symmetric? O A. The distribution of violent-crime rates is symmetric. O B. The distribution of violent-crime rates is skewed left. O C. The distribution of violent-crime rates is skewed right X F 3 attemp
