'''Please read the instructions below, before adding something to the table!'''
Add your row to the table below, following the examples already there. Column 1 = name. Columns 2 + 3 + 4 + 5 + 6 = values for n = 3, namely: difference M of means, estimated standard deviation S' = S / sqrt(n), value of test statistic x = M / S', and the p-values for the Z-test and the T-test, respectively. Columns 7 + 8 + 9 + 10 + 11 = same values for n = 10. Please write all values with exactly three digits after the dot.
Recall: experiment to measure query times for tables with hex vs. integer ids for person names when joining ''acted_in'' and ''has_won'' on their respective first column.
Note: in Wolfram Alpha you can type something like ''P(X >= x) for the standard normal distribution'' or ''P(X >= x) for the t-distribution with ... degrees of freedom'', awesome!
