N= 14 s = 20 h0: σ2 ≤ 500 ha: σ2 ≥ 500 the test statistic for this problem equals

a. 12.68
b. 13.33
c. 13.66
d. 63

Step-by-step explanation:

Hello!

The given hypotheses are to test id the population variance of a population.

H₀: σ²≤500

H₁: σ²≥500

The statistic to use to test the population variance is a Chi-Square:

χ²= ~χ²ₙ₋₁

Data:

n= 14

S= 20

σ²= 500

χ²= = 10.4

None of the given choises is the right answer.

I hope it helps!

the answer is a.
