Answer:
Step-by-step explanation:
Given in the number of hours a group of contestants spent preparing for a quiz
The list shows as follows:
60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61
In ascending order this becomes
x 15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90
F 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2
Thus we have mode =90
All other entries have frequency 1 except 90
