QuestionA chi-square distribution with 4 degrees of freedom is graphed below. The region under the curve to the right of 9 is shaded.
Find the area of the shaded region. Round your answer to three decimal places. \square

Studdy Solution
Calculate the area of the shaded region to the right of 9 by subtracting the cumulative probability from 1:
P(X>9)=1P(X9) P(X > 9) = 1 - P(X \leq 9)
P(X>9)=10.899=0.101 P(X > 9) = 1 - 0.899 = 0.101
The area of the shaded region is approximately:
0.101 \boxed{0.101}
