Nitella [24]

The size of the sample should be obtained at 2401 in order to be 95% confident

Given that:

Margi of error, $ME=0.02$

Population proportion, $p=0.50$

To Find: The size of the sample that should be obtained in order to be 95% confident

Let the size of the sample be n

Using formula,

$n=(p*(1-p))*(z(0.05/2)/ME)^{2} \\n=(0.5*(1-0.5))*(1.96/0.02)^{2} \\n=0.25*9604\\n=2401$

Therefore, the size of the sample should be obtained at 2401 in order to be 95% confident

How do I solve this?

Minchanka [31]

The maximum happens at x = -b/2a

x = -48/2(-16) = 3/2

Now replace x in the equation and solve for y:

y = 48(3/2) - 16(3/2)^2

y = -72 - 36

y = 36

The maximum height is 36 feet.
