### Logic behind hypothesis testing and one-tailed tests

Suppose I have the following: Let's consider a hypothetical experiment to determine whether James Bond can tell the difference between a shaken and a stirred martini. Suppose we gave James Bond a ...

### Autocorrelation of p-values after $n$ observations

For $i = 1, 2, \dots$, let $X_i \sim N(0, 1)$ and $Y_i \sim N(0, 1)$, with all observations independent of each other. Suppose that after observing $X_1, \dots, X_n, Y_1, \dots, Y_n$ we calculate the ...

### Using the critical value from signs test to reject null hypothesis

Question 1 (a) A graduation using $20$ age groups has resulted in $6$ positive and $14$ negative deviations. Carry out the signs test on these data. (b) A graduation covers $20$ age groups. The number ...

### Intuition behind statistical approach for Hypothesis testing

I have studied Hypothesis testing from thinkstats2 which does simulation to estimate p value. For e.g. In coin toss example, we run the simulation, to generate the test statistic i.e. Difference ...
