Claire Oneal · Answer 1

57

Step-by-step explanation:

There are 60 data altogether.

Therefore, n=60

50th percentile = 50% * (n+1)

=50/100 * (60+1)

=30.5

This implies that the 50th percentile is between the 30th and 31st data

30th data = 57; 31st data = 57

since they are the same figure, 50th percentage = 57
