Okay, I guess you can solve this when I tell you this:

Divide 12 by 4 to find your answer because to find these kinds of answer, you need to divide the number of the denominator by the number of eggs or what ever it is.

1/4 of whatever, is $whatever\cdot \cfrac{1}{4}\qquad thus
\\ \quad \\
\cfrac{1}{4}\ of \ 12\implies \cfrac{1}{4}\cdot 12$

A professor believes the students in a statistics class this term are more creative than most other students attending the unive

Answer:

Correct option: B

Step-by-step explanation:

The professor can perform a One-mean t-test to determine whether the average score of the students in his class is more than the average score of all the students attending university.

A t-test will be used instead of the z-test because the population standard deviation is not provided instead it is estimated by the sample standard deviation.

The hypothesis for this test can be defined as follows:

H₀: The average score of the students in his class is not more then the entire university, i.e. μ ≤ 35.

Hₐ: The average score of the students in his class is more then the entire university, i.e. μ > 35.

Given:

$\bar x=40\\SE_{\bar x}=1.63$
