Using the t-distribution, it is found that the 95% confidence interval for the population mean rating for Miami is (5.73, 6.95).
<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 50 - 1 = <u>49 df</u>, is t = 2.0096.
Considering the given sample, the other parameters are given as follows:
Hence, the bounds of the interval are:

Answer:
1.14 miles
Step-by-step explanation:
We have been given that a car rental rents a compact car at a daily rate of $25.20 plus 20c. Mike can afford to spend $48 on the car rental for one day.
To find number of miles, Mike can drive spending $48, we will equate 48 by given expression and solve for c.
Therefore, Mike can drive 1.14 miles and stay within his budget.
