Correct Answer - Option 4 : 7.22, 7
Given:
The given data,
4, 1, 7, 11, 9, 9, 7, 10, and 7
Concept used:
Mode is the most repeated value in a data
Formula used:
Mean = Sum of numbers / Number of observations
Calculations:
Mean = (4 + 1 + 7 + 11 + 9 + 9 + 7 + 10 + 7)/9
⇒ 65/9
⇒ 7.22
Values repeated in the given data,
⇒ 7 = 3 times
⇒ 9 = 2 times
The most repeated term,
Mode = 7
∴ The mean and mode is 7.22 and 7 respectively
