Challenge of the day: Do something unexpectedly nice, it can be anywhere Bonus Challenge: Do as many kind things as possible, then come back here and see who did the most

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.18. what can you conclude? 2(0.18) = 0.36 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 18% of the time, so the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 82% of the time, so the test is not statistically significant. 0.18 > 0.05; the test is statistically significant. p = 1 - 0.18 = 0.82 > 0.05; the test is statistically significant.

What is the function of the organelle labeled a in the diagram?

If the limit, as x approaches infinity (or negative infinity) of a function is equal to a, we say that the line y = a is a of the function f.
