Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
<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 <u>two-tailed 95% confidence interval</u>, with 25 - 1 = <em>24 df</em>, is t = 2.0639.
The other parameters are given by:
.
Hence, the bounds of the interval are given as follows:
The 95% confidence interval is (29.6, 44.4).

Answer:
3 times a number:
3x
Reduced by 10 means we subtract 10:
3x - 10
7 times this quantity:
7(3x - 10)
Therefore, your answer is 7(3x - 10).
