c) Which of the following statements are true about the percentiles of a chi-squared distribution
with 10 degrees of freedom? Answer
The 5th percentile is 31.410
The 95th percentile is 10.851
The 10th percentile is 4.865
The 90th percentile is 37.566 ?
Solution
The 5th percentile is in the left tail. From a chi-squared table where the p value is 0.05, we get
3.94. False.
Going through the others, the second is false, the third is true, and the fourth is false.
So only \"the 10th percentile is 4.865\" is true..
