Answer:

A. Yes, the two corresponding confidence intervals overlap.

Step-by-step explanation:

The correct option is - A. Yes, the two corresponding confidence intervals overlap.

Reason -

P(1) = 45% = 0.45

E(1) = 4.6% = 0.046

Confidence Interval = P(1) ± E(1)

= 0.45 ± 0.046

So, the interval is -

0.45 + 0.046 ≤ P ≤ 0.45 - 0.046

⇒0.496 ≤ P ≤ 0.404 .............(1)

Now,

P(2) = 42% = 0.42

E(2) = 3.6 % = 0.036

Confidence Interval = P(2) ± E(2)

= 0.42 ± 0.036

So, the interval is -

0.42 + 0.036 ≤ P ≤ 0.42 - 0.036

⇒0.456 ≤ P ≤ 0.384 ...............(2)

From equation (1) and (2), we get

The two corresponding confidence intervals overlap.

Solving the quadratic equation we conclude that:

The maximum height is 45ft.
The rocket is 18 seconds in the air.

<h3>How to get the maximum height of the rocket?</h3>

The height of the rocket is defined by the quadratic equation:

$d = 90t - 5t^2$

The maximum height is what we get in the vertex of the quadratic equation, such that for this quadratic equation, the vertex is at:

$t = -90/(2*-5) = 9$

So the maximum height is what we get when we evaluate in t = 9:

$d = 90*9 - 5*9^2 = 45$

The maximum height is 45ft.

Now we need to solve the equation for the largest value of t:

$d = 90*t - 5t^2 = 0$

Rewriting it, we get:

$0 = 90*t - 5*t^2\\\\0 = t*(90 - t*5)$

The maximum solution is what we get when:

0 = 90 - t*5

t = 90/5 = 18

The rocket is 18 seconds in the air.
