Let X1, X2....X7 be i.i.d. N(0,1) random variables

Answer the following questions and give reasons:

i) Find the distribution of x̄.

ii) √(7) x̄.  That's squareroot of 7 times x bar.

iii) 7( x̄.)2 + (X8)2

iv) Y

v) (3[7( x̄.)2 + (X8)2 ])/Y

Let X = E-1 X;.
Li=1
Transcribed Image Text:Let X = E-1 X;. Li=1
Let Y = E(X; – X)².
i=1
Transcribed Image Text:Let Y = E(X; – X)². i=1
