Consider the following results for two independent random
samples taken from two populations.
Sample 1 |
Sample 2 |
n 1 = 50 |
n 2 = 35 |
x 1 = 13.6 |
x 2 = 11.1 |
σ 1 = 2.4 |
σ 2 = 3.4 |
- What is the point estimate of the difference between the two
population means? (to 1 decimal)
- Provide a 90% confidence interval for the difference between
the two population means (to 2 decimals).
- Provide a 95% confidence interval for the difference between
the two population means (to 2 decimals). Use z-table. If
your answer is negative, enter minus (-) sign.
