For the year 2009, the table below gives the percent of people living below the poverty line in the 26 states east of the Mississippi River. Answer the following questions based on this data. State Percent Alabama 7.5 Connecticut 7.9 Delaware 14.9 Florida 13.2 Georgia 12.1 Illinois 10.0 Indiana 9.9 Kentucky 11.9 Maine 13.3 Maryland 10.9 Massachusetts 7.9 Michigan 15.8 Mississippi 9.1 State Percent New Hampshire 14.6 New Jersey 8.3 New York 9.1 North Carolina 12.1 Ohio 13.6 Pennsylvania 10.5 Rhode Island 8.2 South Carolina 12.5 Tennessee 10.0 Vermont 7.3 Virginia 10.4 West Virginia 10.5 Wisconsin 16.1 Q; Construct a relative frequency distribution for this data using 5 classes based on the following structure: Class 1: 7.0 – 8.9, etc. (3 pts.)

Transcript

00:01 In this problem we are told that for the year 2009 we are given a table that gives the percent of people living below the poverty line in the 26 state east of the mississippi river.

00:11 And using the given data we have to construct a relative frequency distribution using the class structure with class interval with class with the first class being 7 .0 to 8 .9.

00:24 Similarly, next class will be 9 .0 to 11 .9.

00:29 The third class will be.

00:30 Be 12 .0 to 14 .9 next it will be 15 .0 to 17 .9 and lastly it is 18 .0 to 20 .9.

00:43 Now from the given information that is given in the question we can say that the number of people or rather the percentage of people that live below the poverty line in the range 7 .0 to 8 .9 are from six states of the west of united states so we will write six for the frequency for the first class next the percentage of the number of states that has a percentage of people living in poverty line living below poverty line in the percentage 9 .0 to 11 .9 are 10 so we will write 10 against the second class similarly for the third class there are eight states that have the poverty that have the percentage of people living below poverty line in the given class and for this fourth class that is from 15 .0 to 17 .9 there are only two states and finally in last class from 18 to 20 .9 percentage there are there is no state that contains or that has this percentage of people living below poverty line so we will write zero against this class now to find the relative frequency we will first find the summation of f so summation of f is given by adding all the values of the frequency for each of the individual classes so it is equal to and the relative frequency for each class is given by dividing the frequency for that class by the total frequency.

02:11 That is, for the first class it is given by 6 divided by 26 multiplied by 100, which after simplifying is equal to 23 percentage...
