<u>Step-by-step explanation</u>
Given that the next model of the sports car will cost 5.2% less than the current model.
The price of the current model=$41000
The price of the next model will be 5.2% less than $41000
There is a $2132 decrease in prize of the sports car.
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.
- t is the critical value.
- n is the sample size.
- 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).
