Answer: 432 ft^2

Step-by-step explanation:

If 1"=3', and the box is 8"x6", then we can simply multiply the 8 and 6 by three. You would get 24 by 18.

Follow this up by the equation a=w*l to get

a=24*18 = 432 ft^2.

A random sample of 17 hotels in Boston had an average nightly room rate of $165.40 with a sample standard deviation of $21.70. T
Citrus2011 [14]

Answer:

•Lower confidence limit = $155.2109

•Upper confidence limit ,= $174.5891

Step-by-step explanation:

We are given:

U = 17

x' = $165.40

S.d = $21.70

a = 10℅ (90℅ confidence interval)

For s.d(x'), we have:

S/√u = \frac{21}{\sqrt{7}}

= 5.2630

Therefore, S.E (x') = $5.2630

At a= 0.10 (90℅ confidence level)

and degree of freedom = 16 (17-1)

Thus, t_1_6_, _0_._1_0 = 1.746

90℅ confidence interval all around sample mean, will be:

(x' ± t_(_n_-_1); a S.E (x')

= (165.4±(174.6)(5.2630)

(165.5±9.189)

($156.2109, $175.5891)
