Final Answer :
False
Explanation :
The value of a chi-squared distribution with 8 degrees of freedom that leaves an area of 0.95 to its left is actually higher than 2.73. The value 2.73 is too low for this percentile in a chi-squared distribution with 8 degrees of freedom; typical values for the 95th percentile are much higher.
