Answer:
We can find the critical value 
And for this case if the confidence increase the critical value increase so then this statement is True
Step-by-step explanation:
For a confidence level given c, we can find the significance level like this:

And with the degrees of freedom given by:
We can find the critical value 
And for this case if the confidence increase the critical value increase so then this statement is True
Answer:
The margin of error for her confdence interval is of 0.3757.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 18 - 1 = 17
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.8982
The margin of error is:

In which s is the standard deviation of the sample and n is the size of the sample.
Standard deviation of 0.55 meters.
This means that 
What is the margin of error for her 99% confidence interval?



The margin of error for her confdence interval is of 0.3757.

Answer:
$255,331
Step-by-step explanation:
Calculation for the estimated price
ln (price) =11.65 +0.000473*square foot
Square feet =1,692
First step is to find the ln (price)
ln (price) =11.65 +0.000473*1,692
ln (price)=12.450316
Last step is to calculate the Estimated price by using calculator to find the exponential of 12.450316
Estimated price=e^(12.450316)
Estimated price=$255,330.99
Estimated price=$255,331 Approximately
Therefore the estimated price of a house that is 1,692 square feet will be $255,331
