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.

Let α = 5% = 0.05
So, 
Since t < t(critical value)
No, New York students are not truly more nerdy than the California students.
Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11
