( n=1 will appear in the window) Enter the second number, 1. Your TI-83 or TI-84 doesn't find the variance for you automatically, but since the standard deviation is the square root of the variance, you can find the variance by squaring the

You could enter 3.165257832², but that's tedious and error prone, as well as being overkill. Descriptive Statistics for a Frequency Distribution Step 1: Enter class marks in L1 and frequencies in L2. Melde dich bei YouTube an, damit dein Feedback gezÃ¤hlt wird. Solution: For the two samples, we have the following summary data: sx1 = 5 sx2 = 7 n1 = 8 n2 = 5 H0: m1 = m2 H1: m1 ¹ m2

For most real-life data sets, the approximation is quite good, and it is very good for moderate to large data sets. Results: Since the p-value is 0.0095 < a = 0.05, reject the null hypothesis with an alpha value of 0.05.
