Question:

Suppose that a sample of size 8 is chosen randomly from a normally distrib¬

uted population with mean 24 and variance 9. The standardized value cor¬

responding to each observed value is computed by subtracting 24 and dividing the result by 3. Let T denote the sum of the squares of the 8 standardized values, and find

(a) P(T> 20.09)

(b) P(2.73 < T < 5.07)

(c) P(T> 2.18).
