Find the critical value or values of x² based on the given information.
H₁:0> 26.1
n = 9
a = 0.01

A) 20.090
B) 2.088
C) 1.646
D) 21.666​

Respuesta :

Using a calculator for the chi-square distribution, the critical value is given by:

A) 20.090

How to find the critical value of the chi-square distribution?

For a chi-square critical value, three parameters are needed:

  • The number of degrees of freedom, which is one less than the sample size.
  • The significance level.
  • The tail.

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.
