Answer 1

Step-by-step explanation:

Calculate the mean value of the following distribution: x: 5 6 7 8 9 f: 4 8 14 11 3

FREQUENCY DISTRIBUTION TABLE IS IN THE ATTACHMENT. From the table : Σfixi = 281 , Σfi = 40.

MEAN = Σfixi / Σfi. MEAN = 281/40 = 7.025.

MEAN = 7.025. Hence, the MEAN value is 7.025 . HOPE THIS ANSWER WILL HELP YOU….
