Answer 1

1. Margin of error = 0.17
2. Sample mean = 1.88

Explanation:

Given:

Sample 1.71 , 2.05

Find:

Margin of error

Sample mean

Computation:

1. Margin of error = (2.05 - 1.71) / 2

Margin of error = 0.34 / 2

Margin of error = 0.17

2. Sample mean = (2.05 + 1.71) / 2

Sample mean = 3.76 / 2

Sample mean = 1.88
