Using the z-distribution, it is found that the lower limit of the 95% confidence interval is of $99,002.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:
In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
The other parameters are given as follows:
Hence, the lower bound of the interval is:
The lower limit of the 95% confidence interval is of $99,002.

A. $330 for the 3 day trip if she does not go over 400 km
b $315 for the cost of the Unlimited Mileage plan.
c. the Unlimited Mileage plan would save you $15 compared to the Standard Daily Rate.
Answer:
A = $1,120 B = $5120
Step-by-step explanation:
1.4/100 = 0.014
0.014 x 4000 = 56
1.4% interest on the $4,000 is $56.
56 x 20 (years) = 1,120
A= $1,120
To get B simply add 1,120 to 4000.
1,120 + 4000 = 5120
B = 5120.
It’s basically 100 multiplied by 2 so 200
Answer:
C
Steps:
Plug in -2 for x in f(x);
f(-2) = (-2)^2 - (-2)
f(-2) = 4 + 2
f(-2) = 6
Then plug in this for f(-2);
6/2 = 3
