Answer #1

Answer:

Correct answer: False

When the standard deviations are equal but unknown, a test for the differences between two population means has n − 1 degrees of freedom.

Explanation:

If two population have equal standard deviation but unknown. Then rhe degree of freedom is = n1 + n2 – 2
