5. In a city, the weekly observations made in a study on the cost of the living index are given in the following table: Cost of living index 140-150 150-160 160-170 170-180 180-190 190-200 Total Number of weeks 5 10 20 20 9 60 2 52 Draw a frequency polygon for the data above.
Here is a data set: 146 132 286 180 165 224 139 153 143 173 138 153 170 217 189 108 146 144 172 158 193 154 297 203 185 224 195 207 Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Your classes should be labeled using interval notation. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. In that the data appears to be discrete, use a closed-interval to label each class.

The lower class limit should be a multiple of the class width. • • For example, if the class width is 10, the lower class limit should be a number like 30 or 40 (depending on the data).
