Answer 1

An appropriate lower class limit for the first class is 120 with a class width of 100.

EXPLANATION:

In the given data:

Minimum value = 124.3

Maximum value = 1345.3

So, the 13 classes are given by:

120 - 220

220 - 320

320 - 420

420 - 520

520 - 620

620 - 720

72- = 820

820- 920

920 - 1020

1020 - 1120

1120 - 1220

1220 - 1320

1320 - 1420
