Question

Use the confidence interval to find the margin of error and the sample mean. (1.57,1.93)

The margin of error is (Round to two decimal places as needed.)
The sample mean is (Type an integer or a decimal.)

Answer 1

The margin of error for the confidence interval (1.57, 1.93) is 0.18, and the sample mean is 1.75. These values are obtained by calculating half of the interval length for the margin of error and averaging the bounds for the sample mean.

Step-by-step explanation:

To find the margin of error and the sample mean from a confidence interval, we take the following steps:

1. 
   
3. 
   
5. 
   
7. 
   

Therefore, the margin of error is 0.18 (rounded to two decimal places), and the sample mean is 1.75.
