I need help with part c

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). Q_1 = 272.8, Q_2 = 388.5, Q_3 = 528.3 (a) Provide an interpretation of these results. Choose the correct answer below. A. 75% of the states have a violent-crime rate that is 272.8 crimes per 100,000 population or less, 50% of the states have a violent-crime rate that is 388.5 crimes per 100,000 population or less, 25% of the states have a violent-crime rate that is 528.3 crimes per 100,000 population or less. B. 25% of the states have a violent-crime rate that is 272.8 crimes per 100,000 population or more. 50% of the states have a violent-crime rate that is 388.5 crimes per 100,000 population or more. 75% of the states have a violent-crime rate that is 528.3 crimes per 100,000 population or more. C. 25% of the states have a violent-crime rate that is 272.8 crimes per 100,000 population or less. 50% of the states have a violent-crime rate that is 388.5 crimes per 100,000 population or less. 75% of the states have a violent-crime rate that is 528.3 crimes per 100,000 population or less. (b) Determine and interpret the interquartile range. The interquartile range is 255.5 crimes per 100,000 populatian. (Type an integer or a decimal.) Interpret the interquartile range. Choose the correct answer below. A. The middle 50% of all observations have a range of 115.7 crimes per 100,000 population. B. All observations have a range of 255.5 crimes per 100,000 population. C. The middle 25% of all observations have a range of 255.5 crimes per 100,000 population. D. The middle 50% of all observations have a range of 255.5 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 crimes per 100,000 population. The upper fence is crimes per 100,000 population. (Round to two decimal places as needed.)

Explanation / Answer

C]

Upper and lower fences outliers from the bulk of data in a set. Fences are usually found with the following formulas:

We have Q3 = 528.3, Inter quartile range (IQR) = 255.5 and Q1 = 272.8

Upper fence = 528.3 + 1.5 * 255.5 = 941.55

Lower fence = 272.8 - 1.5* 255.5 = -110.45.

Thus the upper fence is 941.55 and any scores higher than this should be considered outliers. Here violent-crime rate is 1467, is an outlier rate because our upper fence is 941.55
