50 60
81
Deepak
90 70 60 75
85
80. find the mean score and who has the higher mean score​

Answer 1

Answer:

Deepak

Step-by-step explanation:

To find the mean of a given set of numbers, we must add all the values and divide by the number of numbers. For Arun, we get:

70 + 76 + 78 + 50 + 60 + 81

This is equal to

415

Now, we divide by 6 to get

69 1/6

We do the same for Deepak to get:

90 + 70 + 60 + 75 + 80 + 85

To get

460

We divide by 6 to get

76 4/6 = 76 2/3

We see that Deepak has the higher score and his higher by 7.5
