Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
You need to include an image so I can help
In the scientific value of
5.893 x 10n. The standard value is 0.00005893 what is n?
To better illustrate this
phenomenon, we can explain it further under the rules of scientific notation.
For example.
<span><span>
1. </span><span> 3 x 10^3 = 3 x
100 = 300</span></span>
<span><span>2. </span><span> 3 x 10^-3 = 3 x
0.001 = 0.003</span></span>
Solution:
0.00005893 = 5.893 x 0.00001 =
5.893 x 10^-5
n= ^-5
