Calculate the margin of error of a confidence interval for the difference between two population means using the given information. Round your answer to six decimal places. σ1=7.43, n1=81, σ2=10.61, n2=100, α=0.1
Added by Aaron M.
Step 1
The formula for this is: SE = sqrt[(σ1^2/n1) + (σ2^2/n2)] Substituting the given values, we get: SE = sqrt[(7.43^2/81) + (10.61^2/100)] SE = sqrt[(55.1649/81) + (112.5721/100)] SE = sqrt[0.6808 + 1.1257] SE = sqrt[1.8065] SE = 1.3441 Show more…
