Question

if the means of 5 observation x x + 4 x + 8 x + 12 and X + 6 is 13 find the observation​

Answer 1

Answer:

Step-by-step explanation:

Mean = Sum of the given observations/number of observations.

x + x+4+x+8+x+12+x+6 / 5 =13

=> 5x + 30 = 65

=> 5x = 35

=> x = 7

Thus the observations are

7, 11, 15, 19, 13
