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.
The correct answer to the assertion and reason is D. A is wrong but R is correct
<h3>What is an Assertion?</h3>
This refers to the statement that is meant to be proven by the use of a valid supporting detail.
Hence, we can see the given assertion that modern farming methods decrease the yield of production, there is a need to show a valid reason and this is not done, hence, we can conclude that option D is correct because A is wrong but R is correct.

Explanation:
From the excerpt:
‘A graduate student believes that people consider faces with more contrast between lip color and skin tone as more feminine’ . This is considered as a null and alternative hypotheses.
This is because there is no relationship between how feminine a face is considered to level of contrast between lip color and skin tone and zero effects.
