Question

Values of variable are 10,15,20,25,30 and their corresponding frequencies are 3,p,25,7,5. If their mean is 29.6, find the value of p.

Answer 1

Answer:

108 .... ans.

Step-by-step explanation:

we have the frequencies of these variables are 3,p,25,7,5.

and there mean is 29.6

so,we know that the formula of mean...

mean = (sum of all frequencies)/(no.

of observations)

so,acc.to question..

29.6 = (3+p+25+7+5)/5

29.6×5 = p+40

148-40 = p

so, p = 108 .... ans.
