Answer:
<h2>Odd-degree polynomial function.</h2>Step-by-step explanation:
The given function is attached.
When we analyse function graphs, we can determined if the function is odd-degree or an even-degree.
A real powerful characteristic to know this is by observing the ending points of the function. If both ending points are pointing to the same direction, then it's a even-degree function, but if they are pointing to different directions, then it's an odd-degree functions.
So, in this case, you can observe in the image attached that the ending points of the graph are pointing to opposite directions, one is downwards and the other one is upwards.
Therefore, the graph represents an odd-degree functions.

Answer:
0.5
Step-by-step explanation:
Solution:-
- The sample mean before treatment, μ1 = 46
- The sample mean after treatment, μ2 = 48
- The sample standard deviation σ = √16 = 4
- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.
Cohen's d =
- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:
- Assuming that population standard deviation and sample standard deviation are same:
SD_1 = SD_2 = σ = 4
- Then,
- The cohen's d can now be evaliated:
Cohen's d =
