In order to meet the sample assumption associated with parametric statistics, the number of subjects needed depends on the specific statistical test being used. Generally, the rule of thumb is to have a minimum of 30 subjects in each group being compared.
However, this number may increase or decrease depending on factors such as the effect size, variability in the data, and the statistical power desired.
It is important to have enough subjects so that the data is normally distributed, and there is enough content loaded to meet the assumptions of the statistical test.

Answer:
The required inequality is x > 3.9
Step-by-step explanation:
Consider the provided information.
The closed circle means that the set contain that extreme.
For closed circle we use the inequality "≤" or "≥"
The open circle means that the set does not contain that extreme.
For open circle we use the inequality "<" or ">"
Here, it is given that the graph has an open circle, therefore the required inequality should be "<" or ">"
If the ray moves right, in the usual notation, the real numbers increase to the right, if it moves to left the real numbers decreases.
It is given that the ray moves to right that means the set of numbers bigger than 3.9, that does not contain the number 3.9
Hence, the required inequality is x > 3.9
Where x is any number greater than 3.9.
Answer:
Look at step-by-step solution
Step-by-step explanation:
2(3x-5)=6x+8
First start by dividing two from the left side:
3x-5=3x+4
From there add five and subtracted 3x from both sides:
0=9
Since zero does not equal nine, there is no solution.
Answer:
- 5 does not equal 8
Step-by-step explanation:
Distribute the 2 to get 6x - 5 = 6x +8
6x - 5 = 6x + 8
subtract 6x on both sides you are left with -5 = 8 which is not a true statment.
Since the equation leads to a statment that isn't true, there is no solution.
