Using the t-distribution, it is found that the confidence interval is (14.2, 14.8).
<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.
The critical value, using a t-distribution calculator, for a <em>two-tailed 95% confidence interval</em>, with 18 - 1 = <em>17 df</em>, is t = 2.1098.
The other parameters are given by:
.
Hence, the bounds of the interval are given by:
The confidence interval is (14.2, 14.8).

Step-by-step explanation:
A rational number Q can be expressed in the form
where a and b can take any integer value except b = 0
This is because it would lead to division by zero which is undefined.
