Consider the following hypothesis problem. ​
N = 23
S² = 60
H₀: σ² ≤ 66
H_a: σ² > 66
​
If the test is to be performed at the 5% level, the critical value(s) from the chi-square distribution table is(are)

A) 10.982 and 36.781.
B) 12.338 and 33.924.
C) 12.338.
D) 33.924.

Chi-Square Distribution

A statistical distribution that is used to determine the goodness of fit of an observed distribution to an expected one under the null hypothesis.

Critical Value(s)

Specific point(s) on a distribution curve that define the threshold for rejecting the null hypothesis in hypothesis testing.
