Complete a frequency distribution for the following data that represents the recent sales prices (in $1,000s) of homes in Midwestern County. As this is quantitative data, calculate five classes, report the cumulative frequency, relative frequency, and cumulative relative frequency. Sales price:

115 290 271 267 290
271 242 223 221 269
245 336 236 265 270
249 216 335 237 295

Relative frequency = 0

Cumulative relative frequency

__________________________

200 to 250:

Frequency = 8

Cumulative frequency = 9 + previous cumulative frequency = 8 + 1 = 9

Relative frequency

Cumulative relative frequency

__________________________

250 to 300:

Frequency = 9

Cumulative frequency = 9 + previous cumulative frequency = 9 + 9 = 18

Relative frequency

Cumulative relative frequency

__________________________

300 to 350:

Frequency = 2

Cumulative frequency = 2 + previous Cumulative frequency = 2 + 18 = 20
