Answer 1

Answer:

400,425,175,230,30,200

Answer 2

Step-by-Step Explanation:

Size = 425 - 150 = 275 = 68.75 ≅ 69 (Rounded Value)

                 4             4

Class Interval                   Tally Marks                   Frequency

150 - 219                                IIIII                                     5

220 - 289                               III                                      3

290 - 359                               III                                      3

360 - 429                               IIII                                     4

*In the first frequency the tally marks should be drawn 4 and then a line should be drawn across them but it isn't possible on a Laptop so I drew 5 lines.
