<h3>
Answer: 0.9999</h3>
Explanation:
Having a 1% increase means we go from 100% to 100%+1% = 101% which converts to the decimal form 1.01; note how you move the decimal point two spots to the left to go from 101% to 1.01
A 1% decrease means we go from 100% to 100%-1% = 99% = 0.99
Multiplying 1.01 and 0.99 leads to 1.01*0.99 = 0.9999
Since 0.9999 = 99.99%, this means we have a 100% - 99.99% = 0.01% decrease overall.
Note: the order of the decrease and increase doesn't matter. You could do the decrease first, then the increase, or vice versa.
I think you put each set of data in to l1 and l2 on your calculator nd find the linear regression ( r value) and you can get to the r value by going to stat diagnostic on

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.645.
The sample size and the estimate are given by:
Hence, the bounds of the interval are given by:
The 90% confidence interval is given by: (0.6350, 0.6984).
