if the answer is correct then please follow me
Given : Class size of a distribution = 25
First class interval = 200 - 224
(i) Seven class intervals are as follows :
200 - 224, 225 - 249, 250 - 274, 275 - 299, 300 - 324, 325 - 349, 350 - 374
(ii) Class marks of 200 - 224 : (200 + 224)/2 = 424/2 = 212
Class marks of 225 - 249 = (225 + 249)/2 = 474/2 = 237
Class marks of 250-274 = (250 + 274)/2 = 524/2 = 262
Class marks of 275-299 = (275+299)/2 = 574/2= 287
Class marks of 300-324 = (300 + 324)/2 = 624/2 = 312
Class marks of 325-349 = (325+349)/2 = 674/2 = 337
Class marks of 350-374 = (350+374)/2 = 724/2 = 362
