Hope this helps, you can look it up on google by the way ^^
Answer:
C
Step-by-step explanation:
We can easily rule out B and D because they have dotted lines and both equations are greater than or equal to and less than or equal to.
The appropriate statistical procedure to use here is a two-tailed hypothesis test for the population mean
What is standard deviation?
- The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
- A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Explanation:
- Since we are interested in comparing here the mean heart rate for Canadians who participated in this fitness program, to that of the national average,
- We have to have to conduct a hypothesis test here for sample mean
- Since we are not trying to find the true population mean based on the sample mean, we do not have to construct a confidence interval
- As the sample size, n = 26 < 30,therefore we will use the t-test instead of the z-test.
Therefore, A one-sample t-test for means' is the correct choice.

The rectangle maximum area will be A=9 square units with the length=3 and the width=3.
<h3>What is area of rectangle?</h3>
Area is defined as the space occupied by a plane or rectangle having length and width in two dimensional plane.
It is given that the perimeter of rectangle is P=12
So from the formula of perimeter of rectangle
2(L+W)=12
L+W=6
L=6-W
Now the area of rectangle will be
A=LxW
A=(6-W)W
Now for maximum area we will find the derivative and equate to zero.
So the area will be
Hence the rectangle maximum area will be A=9 square units with the length=3 and the width=3.
