Answer:
Step-by-step explanation:
Given the data: 7.8 7.9 5.8 5.8 5.7 5.6 6.9 8.7 7.9 7.8 7.5 6.7 7.5 8.8 5.7
Rearranged data: 5.6, 5.7, 5.7, 5.8, 5.8, 6.7, 6.9, 7.5, 7.5, 7.8, 7.8, 7.9, 7.9, 8.7, 8.8
The 22nd percentile :
Percentile (i) = (P / 100) * n
Where i = rank, n = Same size ; P = pw cwntile.
P = 22 ; n = 15
i = (22/100) * 15
i = 3.3 rd
The 22nd percentile is equivalent to 4th data in the ordered set = 5.
