28	17	15	22	29	21	23	27	18	12	7	2	9	4
1	8	3	10	5	20	16	12	8	4	33	27	21	15

15	11	9	7	1	5	37	32	28	26	24	20	19	25
19	20	6	9

Answer 1

Class Interval	Tally marks	Frequency
0 - 7	`cancel("||||")` `cancel("||||")` `cancel("||||")`	15
8 - 15	`cancel("||||")` `cancel("||||")` `cancel("||||")`	15
16 - 23	`cancel("||||")` `cancel("||||")` ||||	14
24 - 31	`cancel("||||")` `cancel("||||")` |	11
32 - 39	`cancel("||||")`	5
Total		60
