Answer:

z-interval: (-1.64, 1.64)

90% Confidence interval: (7954,8446)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = $8,200

Sample size, n = 225

Alpha, α = 0.10

Sample standard deviation, s = $750

90% Confidence interval:

$\mu \pm z_{critical}\dfrac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64$

z-interval: (-1.64, 1.64)

$8200 \pm 1.64(\dfrac{750}{\sqrt{25}} ) = 8200 \pm 246 = (7954,8446)$

(7954,8446) is the required confidence interval.

Answer:

Triangular Prism Volume : 560 ft³, Rectangular Prism Volume: 1,400 ft³, and Total Volume of the Composite Figure: 1,960 ft³

Step-by-step explanation:

Triangular Prism Volume Formula: 1/2(L)(W)(H)

1/2(10)(14)(8)

= 560 ft³

Rectangular Prism Volume: L x W x H

10 x 14 x 10

= 1,400 ft³

1,400 ft³ + 560 ft³

= Total Volume of the Composite Figure: 1,960 ft³
