7.75	0	10	5	5	0
8.25	4.5	8.5	5	7	8
4	7.25	7	6.25	7.5	0
9.5	4	6	0	6.25	8.25
6.25	8.25	3	7.5	9.25	7.75
3	7.25	7.25	7	11	0

Answer 1

Hello Sir/ Mam

1. Frequency Distribution

Classes	Frequency
0 - 2.75	5
2.75 - 5.5	8
5.5 - 8.25	18
8.25 - 11	5

2. The distribution gives a rough indication of being a normal distribution.

Lower Class	Upper Boundary	Midpoint	Frequency	Relative Frequency	Cumulative Relative Frequency
0.000	2.750	1.375	5.000	0.139	0.139
2.750	5.500	4.125	8.000	0.222	0.361
5.500	8.250	6.875	18.000	0.500	0.861
8.250	11.000	9.625	5.000	0.139	1.000
Total			36
