Mathematics: Compute the standardized test statistic, Ï‡ 2, to test the claim Ïƒ 2 = 25.8 if n = 12, s 2 = 21.6, and Î± = 0.05.

Compute the standardized test statistic, Ï‡ 2, to

t^2=9.2

Step-by-step explanation:

From the question we are told that

Standard Deviation $\sigma=28.8$

Sample space n=12

s^2= 21.6

Generally the equation for test statistics is mathematically given by

$t^2=frac{(n-1)*s^2}{\sigma^2}}$

$t^2=\frac{(12-1)*21.6}{25.8}$

Therefore the standardized test statistics

t^2=9.2
