Consider the following results for independent random samples taken from two populations.
| Sample 1 | Sample 2 |
| n 1 = 10 | n 2 = 40 |
| x 1 = 22.2 | x 2 = 20.4 |
| s 1 = 2.1 |
s 2 = 4.3 |
- At 95% confidence, what is the margin of error (to 1
decimal)?
- What is the 95% confidence interval for the difference between the two population means (to 1 decimal)? Use z-table. If your answer is negative value, entre minus (-) sign.
