Answer:
The frequency distribution does not appear to be normal.
Step-by-step explanation:
The data provided is as follows:
S = {0.38
, 0
, 0.22
, 0.06
, 0
, 0
, 0.21
, 0
, 0.53
, 0.18
, 0
, 0
, 0.02
, 0
, 0
, 0.24
, 0
, 0
, 0.01
, 0
, 0
, 1.28
, 0.24
, 0
, 0.19
, 0.53
, 0
, 0, 0.24
, 0}
It is provided that the first lower class limit should be 0.00 and the class width should be 0.20.
The frequency distribution table is as follows:
Class Interval Count
0.00 - 0.19 21
0.20 - 0.39 6
0.40 - 0.59 2
0.60 - 0.79 0
0.80 - 0.99 0
1.00 - 1 . 19 0
1.20 - 1. 39 1
The frequency distribution does not appear to be normal. This is because the frequencies does not start and end at almost equivalent points and the mid-distribution does not consist of the highest frequency.
Thus, the frequency distribution does not appear to be normal.
