<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.

Answer:

Step-by-step explanation:

Given : You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.

To Find :What is the chance that our interval estimate does not contain the true population mean?

Solution:

We are given that You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.

So, α=0.01

Significance level indicates a risk of concluding that a difference exists when there is no actual difference.

So, The chance that our interval estimate does not contain the true population mean is 0.01

So, The chance that our interval estimate does not contain the true population mean is $0.01 \times 100 = 1\%$

Hence Option D is true
