Question

Complete parts (a) through (d) Q_1 = 272.8, Q_2 = 388.5, Q_3 = 529.1 25% of the states have a violent-crime rate that is 272.8 crimes per 100,000 population or lees. 50% of the states have a violent-crime rate that is 75% of the states have a violent-crime rate that is 529.1 comes per 100,000 population or less. 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 25% of the states have a violent-crime rate that is 529.1 crimes per 100,000 population or less. 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 i 75% of the states have a violent crime rate that is 529.1 crimes per 100,000 population or more. Determine and interpret the interquartile range. The interquartile range is 256.3 crimes per 100,000 population the interquartile range. Choose the correct answer below. The middle 50% of all observations have a range of 256.3 crimes per 100,000 population. The middle 25% of all observations have a range of 256.3 crimes per 100,000 population. All observations have a range of 256.3 crimes per 100,000 population. The middle 50% of all observations have a range of 115.7 crimes per 100,000 population. 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 crimes per 100,000 population, he upper fence is crimes per 100,000 population.

Explanation / Answer

Q1=272.8,Q2=388.5,Q3=529.1

b)IQR=529.1-272.8=256.3

c)Lower Fence=Q1-1.5*IQR=272.2-1.5*256.3=-112.25

Upper Fence=Q3+1.5IQR=529.1+1.5*256.3=913.55

Hence 1496 is an outlier as it is not within the lower and upper fence range
