Answer 1

Answer:

If the mean of five observations x,x+4,x+8,x+12 and x+16 is 13,then find the mean of the observations

Step-by-step explanation:

formula of mean is xbar = sigma fixi by sigma fi

Answer 2

Answer:

5, 9, 13, 17, 21

Step-by-step explanation:

Mean = Sum of observations/

no. of observations

13 = x+ x+4+x+8+x+12+x+16/5

65 = 5x + 40

25 = 5x

x = 5

x+4 = 9

x+8 = 13

x+12 = 17

x+16 = 21
