Answer 1

Arranged in ascending order, 162, 167, 289,353, 375,434,499,733, 739, 846, 967, 986, 1021, 1145,1159,1426, 1455, 1563,1740,1788, 2297, 2467, 2600, 3373,3673, 4064, 4231,4370, 4503, 4628, 4890, 5395, 5729, 5805, 5817, 5927. Let we have to construct a frequency distribution with 6 classes 5927-162 We have, Class Width= No.of classes we need 5927-162 960.83 6 (we can keep aprroximately 1000 class width) So we have following frequency distribution table, Class Count 13 0-1099 7 1100- 2199 2200-3299 3 3300-4399 4 4400-5499 5500 6599 4 Total 36 LO st
