we know that
m∠ZWY=m∠WXY --------> given problem
so
In the right triangle ZWY
In the right triangle XWY
<u>Find the value of b</u>
<u>Applying the Pythagorean Theorem</u>
In the right triangle XWY
therefore
<u>the answer is the option</u>
D) 9.4 units
The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be .
Suppose X has a distribution with mean and standard deviation
then,
the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to
Symbolically, we write it as:
A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.
The mean and standard deviation of the x sampling distribution for each of the following sample sizes.
If N=41
If N=130

Answer:
it'll be a graph like this. the blue line is y<-x+2 and you would shade everything below this line because it's less than. the green is y>x-3 so you would shade everything above this line because it is greater than.
