Company A-> charges $75 and unlimited millage.
Company B-> initial fee $55 and charges +$0.8 for every mile driven.
The inequality that represents for what millage will company A charges less than company B is:
Let m be the number of miles
[tex]\begin{gathered} 75<55+0.8m \\ 75-55<0.8m \\ 20<0.8m \\ \frac{20}{0.8}For 25 miles company A will charge less than company B.
Answer:
A normal distribution or z-test is used to construct a confidence interval.
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= $3120
Sample size, n = 40
Population standard deviation, σ = $677
The distribution of earnings of college is a normal distribution.
Conditions:
- Since we are given the population standard deviation and the the sample size is also greater than 30.
Conclusion:
Thus, we use a normal distribution or z-test to construct a confidence interval.
