1.	The mean of the following data is 7.5. Find the value of P.x=3, 5, 7, 9, 11, 13f=6, 8, 15, P, 8, 4
Answer» Σfi = 41+p\xa0Σfixi = 303+9pMean = Σfixi / Σfi7.5 = (303+9p) / (41 +p)7.5(41 +p) = 303 +9p307.5 +7.5 p = 303 +9p307.5 - 303 = 9p - 7.5 p4.5 = 1.5 pp = 4.5 / 1.5 = 3P = 3Hence, the value of p is 3.
