Jackson sampled 101 students and calculated an average of 6.5

ozzi

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:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

For this problem, the parameters are given as follows:

$\overline{x} = 6.5, s = 2.4, t = 1.984, n = 101$

Hence the bounds of the interval are:

$\overline{x} - t\frac{s}{\sqrt{n}} = 6.5 - 1.984\frac{2.4}{\sqrt{101}} = 6.03$

$\overline{x} + t\frac{s}{\sqrt{n}} = 6.5 + 1.984\frac{2.4}{\sqrt{101}} = 6.97$

The 95% confidence interval for the average number of hours of sleep for working college students is between 6.03 and 6.97 hours.
