The 95% confidence interval for the slope will be B. (-0.308,-0.019).
<h3>How to calculate the interval?</h3>The confidence interval based on the information and diagram will be:
= -0.1636 + 2.228 × 0.06488
= 0.019
Also, -0.1636 - 2.228 × 0.06488
= -0.308
In conclusion, the correct option is (-0.308,-0.019).

Answer:
Eq.
y = -6(x-3.7)^2 + 82.14
the value t = 3.7 represents the maximum amplitude of the rocket in-flight.
Step-by-step explanation:
The standard equation of the parabola is written as
ax^2 +bx +c = 0
But we can rewrite it in vertex form. (See attached picture.)
y = a(x-h)^2 + k
If we look at the question, we can see that the vertex is
(h,k) = (3.7 , 82.14)
y = -6(x-3.7)^2 + 82.14
the value t = 3.7 represents the maximum amplitude of the rocket in-flight.
