Answer:
It is an unusual result contradicting the national survey.
Step-by-step explanation:

The professor's survey showed that 96/244 = 39% drink.
The professor's survey deviated from the national survey is 5% (44% - 39%) representing about 0.25% (5% squared) variance.

Answer:
Step-by-step explanation:
The derivative of your function is ...
y' = dy/dx = 2e^(2x) +6
At x=0, the value is ...
y'(0) = 2e^0 +6 = 8
dy = 8·dx
__
Δy = y'(0)·Δx
Δy = 8(.03)
Δy = 0.24
