Given,

Mean = 12.58

= 12.58

524 + 7p = 12.58 (50)

7p = 629 – 524

p = = 15

If the mean of the following data is 15, find p.

x :	5	10	15	20	25
y :	6	p	6	10	5

Find the value of p for the following distribution whose mean is 16.6

x :	8	12	15	p	20	25	30
y :	12	16	20	24	16	8	4

Find the missing frequency (p) for the following distribution whose mean is 7.68.

x:	3	5	7	9	11	13
