The length of XY equals infinity
Answer:
a) P(12≤χ²≤24)=0.690
b) k=35.85
c) Median=18.34
Step-by-step explanation:
<em>The question is incomplete: "Use the calculator provided to solve the following problems. Suppose that χ² follows a chi-square distribution with 19 degrees of freedom. Compute P(12≤χ²≤24) . Round your answer to at least three decimal places.</em>
<em>Suppose again that χ² follows a chi-square distribution with 19 degrees of freedom. Find k such that P(χ²>k)=0.025. Round your answer to at least two decimal places.</em>
<em>Find the median of the chi-square distribution with 19 degrees of freedom. Round your answer to at least two decimal places."</em>
Compute P(12≤χ²≤24)
Find k such that P(χ²>k)=0.025
The median of the chi-square is:
So you have 10 = 2g - 8
Add 8 in both sides.
10 = 2g - 8
+8 + 8
Now, you have 18 = 2g.
Divide 2 on both sides.
18 = 2g
/2 /2
g = 9
