Question details

1. Construct a cumulative frequency distribution of the 20 brain volumes(cm3) listed below.
Use the classes 900-999, 1000-1099, and so on. (6-classes)
1005   963 1035 1027 1281 1272 1051 1079 1034 1070 1173 1079 1067 1104 1347 1439 1029 1100 1204 1160.Also find relative frequency for each class interval?


2. Use data above in question 1 to build the frequency polygon. Is the distribution symmetric?
