Question

the mean of the following distribution is 2.6 find the value of y frequency 4 5 y 1
​

Answer 1

Answer:

the answer is 0.4

Step-by-step explanation:

given mean of all observation is 2.6

y=?

sum of observations/number of observation=2.6

4+5+y+1/4=2.6

10+y/4=2.6

10+y=2.6x4

10+y=10.4

y=10.4-10.0

y=0.4
