Response:
I believe the answer might be either the second or the fourth option.
Apologies if this isn't accurate.
Detailed explanation:
The highest 5% of scores corresponds to the 95th percentile, meaning the cutoff score

is defined as

When transformed into the standard normal distribution,

A cumulative probability of 95% corresponds to a z-score of approximately

, indicating that the cutoff score is likely around
Answer:
Choice A.
Detailed explanation:
The provided expression is
where,
.
Our goal is to identify an expression that matches the one given.
The current expression can be expressed as
Thus, the right choice is A.
Answer:
In conclusion, the answer is C.
Step-by-step explanation:
A=30000+0.03S and B=25000+0.05S.
Setting A equal to B gives us 5000=0.02S, which results in S=$250000 for equal earnings.
The slope of A is less steep compared to that of B. Beyond this S value, B compensates more than A, while underneath it, A compensates more than B.
Therefore, the correct answer is option B. (At S=0, it is evident that A is superior to B. If S=$300000, A yields $39000 and B yields $40000).
