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.
