Consider a normal population distribution with the value of σ known. (a) what is the confidence level for the interval x ± 2.81σ
sammy [17]
The confidence level would be 99.5%.

When we know the confidence level, we find the z-score by:
Dividing the CL by 100;
Subtracting this result from 1;
Dividing this result by 1;
Subtracting this result by 1.

Algebraically, this looks like:
1-(\frac{1-(\frac{CL}{100})}{2})

Using a z-table (http://www.z-table.com), we see that a z-score of 2.81 results in an area under the curve of 0.9975, so we now have
1-(\frac{1-(\frac{CL}{100})}{2})=0.9975

To begin solving this, we will subtract 1 from both sides:
-(\frac{1-(\frac{CL}{100})}{2})=-0.0025
\\
\\(\frac{1-(\frac{CL}{100})}{2})=0.0025

We will now multiply both sides by 2:
1-\frac{CL}{100}=0.005

Subtract 1 from both sides:
-\frac{CL}{100}=-0.995
\\
\\\frac{CL}{100}=0.995

Multiply both sides by 100:
CL = 99.5

What is the difference when the product of 0.3 and 0.4 is subtracted from the sum of 0.3 and 0.4?​
Rudik [331]

Answer:

0.58

Step-by-step explanation:

The first approach to solving the question above is to find the product of 0.3 and 0.4 thus:

0.3 \times 0.4 = 0.12

Next step is to find the sum of 0.3 and 0.4 thus:

0.3 + 0.4 = 0.7

The final step is to find the difference between the two results. Thus:

0.7 - 0.12 = 0.58

Therefore, the product of 0.3 and 0.4 subtracted from the sum of 0.3 and 0.4 is 0.58
