Perform a hypothesis test on two independent samples: A researcher using an independent measure design to compare two treatments obtained the following data, use a two-tailed independent-measures hypothesis testing using an σ = 0.05) Treatment 1: n=10, x=78 ss=96 Treatment 2: n=10, x=82,ss=87
a. What is the variance of treatment 1?
b. What is the variance of treatment 2?
c. What is the pooled variance?
