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
