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). Upper Q1 equals 272.8, Upper Q2 equals 387.9, Upper Q3 equals 529.7. (a) Provide an interpretation of these results. Choose the correct answer below. A. 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 387.9 crimes per 100,000 population or more. 75% of the states have a violent-crime rate that is 529.7 crimes per 100,000 population or more. B. 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 387.9 crimes per 100,000 population or less. 25% of the states have a violent-crime rate that is 529.7 crimes per 100,000 population or less. 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 387.9 crimes per 100,000 population or less. 75% of the states have a violent-crime rate that is 529.7 crimes per 100,000 population or less. (b) Determine and interpret the interquartile range. The interquartile range is 256.9 crimes per 100,000 population. (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 256.9 crimes per 100,000 population. B. The middle 50% of all observations have a range of 115.1 crimes per 100,000 population. C. The middle 25% of all observations have a range of 256.9 crimes per 100,000 population. D. All observations have a range of 256.9 crimes per 100,000 population. (c) The violent-crime rate in a certain state of the country in that year was 1,496. Would this be an outlier? The lower fence is nothing crimes per 100,000 population. The upper fence is nothing crimes per 100,000 population. (Round to two decimal places as needed.)
