Answer:
B. One of the populations is normally distributed.
Step-by-step explanation:
To test a claim about two population standard deviation or variance, it is imperative that the data meets certain requirements which include :
Randomness : Data must not be biased as such it must be drawn as a random sample from a larger group.
The data must be independent. That is not related to one another, the outcome of one should not rely on the outcome or value of another.
Both groups must be drawn From a population which is normally distributed.
One group being normally distributed by stribuyed while the other isn't a requirement for hypothesis testing in this scenario.
The key features of the graph include the fact the graphs are periodic.
<h3>How to illustrate the graph?</h3>
It should be noted that a graph is a diagram that represents ban interrelations between variables.
The tan graph is simply the visual representation of the tangent function for a range of angles.
In this case, the graphs have been attached and it can be seen that the tan graph repeats every 180° and is not a continuous curve.

Answer:
$1799
Step-by-step explanation:
We simply work backwards and write out an equation.
Lets call the initial price P.
First we have 15% off the initial price P which means that we are only paying 85% of the initial price: .85*P.
Next we use a coupon for 20% off the reduced price which means we only pay 80% of the reduced price: .80 * (.85 * P)
We know that the price paid was $1223.32, set that equal to .80 * (.85 * P)
and we find that P is $1799
I believe the correct answer from the choices listed above is option 2. The element that is found in both carbohydrate and water is the element oxygen. Carbohydrates contain aldehydes and ketones which has oxygen on them and water has hydrogen and oxygen. So, it must be oxygen.
