The mean of 5 observations is 4.4 and variance is 8.24 . If three of the five observations are 1,2 and 6, then what are the other two observations?

Options

  1. A9,16
  2. B9,4
  3. C81,16
  4. D81,4

Correct answer

B. 9,4

Step-by-step solution

Given: n=5 aligned & x =4.4 & ^2=8.24 & x= x x & x=5 4.4=22 & also 1+2+6+p+q=22 & p+q=13 & 9,4=p, q . aligned
