Apsychologist is conducting a study to learn about the difference between two population means, ? 1 - ? 2 using a two-independent samples t procedure. the two sample standard deviations are s1 = 4.0 points and s2 = 3.0 points and the sample size for the group 1 was more than the sample size for group 2. which value is the only reasonable value for the pooled estimate of the common population standard deviation?
2.3 points
3.3 points
3.5 points
3.7 points
4.9 points
