Question

Using two independent samples, two population means are compared to determine if a difference exists. The number in the first sample is fifteen and the number in the second sample is twelve. How many degrees of freedom are associated with the critical value

Answer 1

Degrees of freedom=25

Step-by-step explanation:

The formula for degree of freedom for two population sample is :

Degree of freedom=n1 + n2 - 2

N1= first sample

n2=second sample

According to the question, n1=15 and n2=12

So,

Degree of freedom= 15 + 12 - 2⇒ 25
