Answer:
The correct option are: (A), (B), (C) and (E).
Step-by-step explanation:
The One-Way ANOVA is a statistical test used to compare the three or more population means.
The hypothesis is:
<em>H</em>₀: The population means are equal, i.e. μ₁ = μ₂ = μ₃ =...= μₙ
<em>H</em>ₐ: At least one of the population mean differ.
The Assumptions of One-way ANOVA are:
- The samples selected from each population are independent of each other.
- The population distribution of the dependent variables follow Normal distribution.
- The population variances are always equal for all the groups.
Thus, the correct option are: (A), (B), (C) and (E).
Answer:
D
Step-by-step explanation:
Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)

must be continuous in order to be differentiable, so we need to have

By its definition,
, and


so that
.
We want the derivative to exist at
, which requires that we pick an appropriate value for
so that
is also continuous. At the moment, we know
such that

We have


so that
(which means we need to pick
) and so 
Try this option:
1. according to the graph no points of intersection between function and X-axis, it means, that
2. D<0 and no real solutions. In other words function has two complex solution.
Answer: 2.
