92. Confidence intervals Two means Independent samples Part 1

Lecture Resources: Exercise: Exercise Solution: In our last lesson we learned about confidence intervals for two means based on the pendant samples in this video. We will explore independent samples as we said earlier. There are three subcase is known population variances unknown population variances but assumed to be equal and unknown population variances that are assumed to be different here. We will focus on independent samples with known population variances. All right let's jump right into the
