Answer:
Formal operational
Explanation:
Jean Piaget develop a theory of cognitive development, according to which, children and teenagers go through different stages in the process of cognitive development. Each stage is qualitatively different from each other and as they go through stages, their thinking go through changes, from thinking based on actions to thinking based on ideas.
The last stage of his theory is called the formal operational stage and it takes place between age of 12 and up. During this stage, adolescents start to think abstractly and reason about hypothetical problems, they are also able to formulate hypothesis and test them in order to find theories and solutions to different problems based on abstract thought.
In this example, Raj is 12 years old and uses statistical analysis and scientific principles to predict the course of weather in New York. We can see that <u>he is thinking in an abstract way and using abstract tools such as statistical analysis in order to create his theory. </u>Therefore, because of his age and the type of thinking he is having, he is most likely in the formal operational stage of development.
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.
