Observed t = Type your answer here The decision is to Choose your answer here fail to reject the null hypothes is reject the null hypothesis.
Suppose you want to determine whether the average values for populations 1 and 2 are different, and you randomly gather the following data. Test your conjecture, using a probability of committing a Type I error of .01. Assume the population variances are the same and x is
Sample 1:
| 2 | 10 | 7 | 8 | 2 | 5 |
| 9 | 1 | 8 | 0 | 2 | 8 |
| 11 | 2 | 4 | 5 | 3 | 9 |
Sample 2:
| 10 | 12 | 8 | 7 | 9 | 11 |
| 9 | 8 | 9 | 10 | 11 | 10 |
11 10 7 8 10 10
Find the t-score to make a conclusion.
(Round your answer to 2 decimal places, e.g. 1.75. Enter negative amount using a negative sign preceding the number e.g. -1.75.)
