Question

find the mean of the following distribution ​

Answer 1

Answer:

Here's your answer

Mean = 75

Step-by-step explanation:

xi = 5 , 10 , 15 , 20 , 25

fi = 2 , 8 , 15 , 10 , 5

Now,

∑xi = 75

∑fi = 40

Now , mean is given by

Mean = ∑xi x ∑fi /∑fi

= 75 x 40 / 40

= 3000 / 40

=> Mean =75

Hope you understand.
