Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15

Answer:
3040
Step-by-step explanation:
given arithmetic progression is
70,100,130,...
here
first term (a)=70
common difference (d)=100-70=30
number of term n=100
using the formula of arithmetic progression
an=a+(n-1)d
a100=70+(100-1)30
a100=70+99×30
a100=70+2970
a100=3040
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).
