Question

Asked Nov 4, 2019

In a sample of 30 participants, a researcher estimates the 95% CI for a sample with a mean of Μ_{1}-Μ_{2} = 0.7 and an estimated standard error for the difference *s _{Μ1-Μ2}* of 0.2. What is the confidence interval at this level of confidence?

Step 1

From the given question

Sample size (n) =30, mean difference (M_{1}-M_{2}) =0.7 and standard error difference (S_{M1-M2}) =0.2.

Step 2

Formula for confidence interval (CI) is

Step 3

Let substitute these values in equation...
