Consider the following partially completed frequency table:
Class xi fi Relative fi Fi Relative Fi
[129; 134) 2
[134; 139) 7 *
[139; 144) 10
[144; 149) 8
[149; 154) 3
Determine the missing value indicated by the “*”.
0.4
10.6333
0.2333
0.3
To determine the missing value indicated by the "*", we need to calculate the relative frequency for the class [134; 139).
The total frequency, ∑fi, is the sum of all the frequencies given, which is 2 + 7 + 10 + 8 + 3 = 30.
The relative frequency (fi/∑fi) for the class [134; 139) can be calculated as follows:
Relative fi = 7/30 = 0.2333
Therefore, the missing value indicated by the "*" is 0.2333.
