Given the sample 6, −1, 6, 11, −6, −7, add one more sample value that will neither change the median nor the range. Round to two decimal places as necessary.

If this is not possible, indicate "Cannot create sample".

Because the two variables are on different measurements, the scores need to be converted into Z scores so the variables can be examined together. To calculate Z scores, we need the mean and standard deviation for each variable. Using the data...
