Using the t-distribution, the 95% confidence interval for the average number of hours of sleep for working college students is between 6.03 and 6.97 hours.
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- s is the standard deviation for the sample.
For this problem, the parameters are given as follows:
Hence the bounds of the interval are:

Answer:
Here's one way to do it.
Step-by-step explanation:
-24 ÷ (-4)
