Can you please provide a math formula or an Excel example (math operations and Excel functions jointly used) to compute the probability (area) of overlap of two normal distributions having EQUAL variance?
The original data are as follows:
Mean 1 = 1145 Mean 2 = 1214 Standard Error of both distributions = 276 Variance = Standard Error^2 * square root of sample size = 276^2 * sqrt(30) = 417 233.14
There is one good example made by "wolfies" here.
He gives the formula to compute C and the formula together with Excel Erf function to compute the probability (area) of overlap of two distributions but it is for UNEQUAL variance.
I wish he could see my post.
