Two samples, each with n = 5 scores, have a pooled variance of 40.What is the estimated standard error for the sample mean difference? Group of answer choices 10 4 8
Added by Daniel B.
Step 1
The formula is: \[ SE = \sqrt{\frac{s^2_p}{n_1} + \frac{s^2_p}{n_2}} \] Where: - \( SE \) is the standard error of the difference between the means. - \( s^2_p \) is the pooled variance. - \( n_1 \) and \( n_2 \) are the sample sizes of the two groups. Given: - Show more…
