A group of 50 New York psychology students got a mean score of 530 on the psychology GRE with a standard deviation of 80. These
lesantik [10]

Answer: No, New York students are not truly more nerdy than the California students.

Step-by-step explanation:

Since we have given that

Number of students in a group = 50

Mean score of New York psychology = 530

Mean score of California psychology = 515

Standard deviation = 80

So, we will find t-distribution first.

t=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\t=\dfrac{530-515}{\dfrac{80}{\sqrt{50}}}\\\\t=1.32

Let α = 5% = 0.05

So, t_{\alpha,2}=2.920

Since t < t(critical value)

No, New York students are not truly more nerdy than the California students.

mestny [16]

\huge\boxed{\text{Dominic}}

In this problem, 0 represents the sea level. Since Dominic is 175 feet below the surface (sea level), his current location is at -175 feet.

The same concept can be applied to Karen, who is at -138 feet.

We need to find who is lower, or farther below 0. This means the answer is \boxed{\text{Dominic}}.
