Calculate the mean, variance and standard deviation for the following distribution :
   

Text Solution

Verified by Experts

With the given distribution , `x_i = 35, 45, 55, 65, 75, 85, 95`
`f_i = 3, 7,12, 15,8,3,2`
`:. x_i f_i = 105, 315,660,975,600,255,190`
`:. sum f_i = 50`
`sum x_i f_i = 3100`
`:. Mean(barX) = (sum x_i f_i)/(sum f_i) = 3100/50 = 62`
Now, `|x_i - barx| = 27, 17,7,3,13,23, 33`
