Answer 2

Step-by-step explanation:

First of all find the submission of f i.e. add all the values of f and write down below the f column vertically then make another column of fx i.e. the multiplication of values of x and values of f.

now write down the submission fx down below the fx column.

now by putting the formula for finding the mean i.e.

Mean=submission of x / submission of fx

therefore, 7.68=41+p/ 303+9p

now you can solve this equation and get the value for p.
