1. What is the difference between a test of independent means and a test of matched means?

2. How would I calculate a test of matched means? what is the“matched” means?

3. Do you think both these tests ( a test of independent means and a test of matched means) are reasonable? Fair? Why or why not? Common concerns might be assumptions of the test being met, the practicality of the test, etc.

Suppose independent random samples that are taken to test the difference between the means of two populations (n1 = 66 and n2 =46). The variances of the populations are unknown but are assumed to be unequal. The sample standard deviations are s1=82 and s2=68. The appropriate distribution to use is the: A) t distribution with df = 110 B ) t distribution with df = 107 C) t distribution with df = 106 D) F distribution with numerator df =...
