The Affordable Care Act created a market place for individuals to purchase health care plans. A sample of premiums for the bronze level health insurance are given in the table. Create a frequency distribution, relative frequency distribution, and cumulative frequency distribution using 5 classes. $138 $238 $282 $254 $223 $275 $180 $194 $220 $228 $198 $178 $289 $162 $181 $126 $138 $140 $233 $235 $205 $203 $258 $129 $177 $161 $177 $243 $274 $172 $179 $296 $134 $164 $247 $140 Class limits Frequency Relative frequency Cumulative frequency $-$ $-$ $-$ $-$ $-$

Expert Solution

Step 1

Given data:

$138 $238 $282 $254 $223 $275 $180 $194 $220 $228 $198 $178 $289 $162 $181 $126 $138 $140 $233 $235 $205 $203 $258 $129 $177 $161 $177 $243 $274 $172 $179 $296 $134 $164 $247 $140

Number of classes = 5

To create a frequency distribution, relative frequency distribution, and cumulative frequency distribution:

$\begin{array}{rcl} C l a s s w i d t h & = & \frac{M a x i m u m - M i n i m u m}{N o . o f c l a s s e s} \\ = & \frac{296 - 126}{5} \\ = & \frac{170}{5} \\ = & 34 \end{array}$

Frequency distribution table for the data is given below:

Frequency is the number of occurrences of a value a class interval.

Class limits	Frequency
126 - 160	7
161 - 195	11
196 - 230	6
231 - 265	7
266 - 300	5
Total	36
