If the mean of the following frequency distribution is 8, find the value of p.
Let’s draw the table and calculate the relative value of variables ∑xi×fi
By putting the formula of mean we get;
Mean = (given)
So we have,
303 + 9P = 8 (41 + P)
303 + 9P = 328 + 8P
9P-8P = 328-303
P = 25
Hence the value of the P is 25.
