Answer:0.0228
Explanation:
Assuming the letter of Alphabet A is a random variable which represents the small bowl and the letter of Alphabet B is the random variable which represents the large bowl.......
Therefore, the total amount of large bowl and small bowl is B+A and the difference between the large bowl and the small bowl is B-A....................
The first thing to do is to find the variance followed by the determination of the z-score.
(A). Variance= σ= √( σ^2(B) + σ^2(A)..........-----------------------------------------------------------------------------------(1)..
Then,
σ= √(0.4^2 + 0.3^2).
σ= 0.5.
(B). Hence, we calculate for the z-factor.
Therefore, z= 0 - 1/ 0.5.
= -2.
So, P(B - A < 0) = 0.0228.

Answer:
The correct answer is:

Explanation:
The dependent variable in a research investigation refers to the information that will vary according to the independent variables that might be applied influencing the results of the experiment.
In this case, it is expected that the dependent variable, which consists of the test scores, differ according to the independent variables which would be the changing conditions for the application of the test.
