Using a calculator for the chi-square distribution, the critical value is given by:
A) 20.090
<h3>How to find the critical value of the chi-square distribution?</h3>
For a chi-square critical value, three parameters are needed:
- The number of degrees of freedom, which is one less than the sample size.
In this problem, we have a one-tailed test(as we are testing if the mean is greater than a value), with a significance level of 0.01 and 8 df, hence, using a calculator, the critical value is of 20.09, hence option A is correct.

Answer:
Divide 11 by 10 . Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (1) by the divisor 10 . Subtract 10 from 11 . :) Hope this helps!
If r=0.01 the answer would be 50 because you're multiplying 5000×0.01.
The sum of all the interior angles in a hexagon is 720°, so if you add up all the angles and then take them away from 720, you'll get your answer:
152 + 85 = 237
237 + 85 = 322
322 + 125 = 447
447 + 135 = 582
So 720 - 582 = 138°, which is your answer. I hope this helps!
I completely forgot how to do this but maybe multiply the angles I’m so sorry
