Answer:

mean = 148.61

Step-by-step explanation:

C. I.          ∑fi        xi        ∑xifi

0-50        17       25         425

50-100    35       75        2625

100-150   43       125       5375

150-200  40       175       7000

200-250  21      225      4725

250-300  24     275      6600

total        180                 26750

mean = \frac{∑xifi}{∑fi}

         = \frac{26750}{180}

         = 148.61
