    What is the difference between a Menu 6,6,3 and Menu 6,7,3. one is confidence interval, and the other is a Stat test, but I dont know what that means.

    Wouldn't the variances/standard deviations be squared? Isn't that the formula?

      Variance is the standard deviations squared or standard deviation is the square root of the variance

    Hi. How do you find the standardized test statistic on the tinspire when m1-m2 is not equal to 0? lets say that m1-m2 was greater than 7000. How do we plug that into the calculator?

      You would have to use the formula and plug it into the calculator. The numerator would need to be in ( ). Unfortunately, the calculator only tests for their being no difference and not a difference like 7000. You would use the formula in the video, and just plug in the values given.
