Answer:
test statistic = 12.115
Step-by-step explanation:
Given data :
std = 2.1 years
n = 10
( std )^2 = 4.41
<u>determine the test statistic</u>
apply a two-tailed test ( chi squared test for one population variance )
test statistic
λ^2 =
( Referring to Exhibit 11-1 )
= ( 10 - 1 )*(2.1)^2 / 3.2761
= 12.115
