19.1 should be your answer
Answer:
Step-by-step explanation:
From the given data
we observed that the missile testing program
Y1 and Y2 are variable, they are also independent
We are aware that
have distribution with 1 degree of freedom
and has x^2 with 2 degree of freedom
Since we have to find the density formula
We use method of transformation
There inverse function is
We derivate the fuction above with respect to u
Therefore,
Isolate z by itself:
To simplify variables with powers, subtract the smaller power from the bigger power:
The exponent will be
-3.
