Answer 2

Given:

Mean value=25

To find:

The value of p

Solution:

The value of p is 98.

We can find the value of p by following the given steps-

We know that the mean of a frequency distribution can be obtained by dividing the sum of all the given frequencies by the number of observations in the distribution.

The frequency given to us is as follows-

5, 6, 10, 6, p

The mean of the frequency distribution is 25.

The number of observation=5

Mean of the distribution=Sum of all frequencies/ Number of observations in the distribution

On putting the values, we get

25=(5+6+10+6+p)/5

25×5=(5+6+10+6+p)

125=27+p

125-27=p

98=p

Therefore, the value of p is 98.
