Document Summary
Chapter 10: the t test for two independent samples. There are several possible solutions to the matchstick problem in the chapter 10 preview but all involve destroying two of the existing squares. One square is destroyed by removing two matchsticks from one of the corners and a second square is destroyed by removing one matchstick. The three removed matchsticks are then used to build a new square using a line that already exists in the figure as the fourth side. One solution is shown in the following figure. Original pattern with 5 squares (arrows note matchsticks to remove) When the two samples come from populations with the same mean (when h0 is true), the standard error indicates the standard amount of error (distance) between two sample means: a. The size of the two samples influences the magnitude of the estimated standard error in the denominator of the t statistic.
