the Wall Street Journal reported that automobile crashes cost United States $162 billion annually. The average cost per person f

Tanya [424]

Answer:

a) Margin of error = 166.311

b) sample size ≥ 62

Step-by-step explanation:

Given:

Average cost = $1599

Sample size = 50 persons

Standard deviation = $600

Confidence level is 95%

a) Margin of error = $z\frac{\sigma}{\sqrt{n}}$

Now for confidence level of 95% z-value = 1.96

Thus,

Margin of error = $1.96\frac{600}{\sqrt{50}}$

Margin of error = 166.311

b) For Margin of error ≤ 150

$z\frac{\sigma}{\sqrt{n}}$ ≤ 150

$1.96\frac{600}{\sqrt{n}}$ ≤ 150

$1.96\frac{600}{150}$ ≤ √n

√n ≥ 7.84

n ≥ 61.4656

Therefore,

sample size ≥ 62

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−5).

Zolol [24]

Hi! the answer should be 104

----

Formula: h(g(x))

1) First you want to take the -5 and plug that into the given equation for g(x)

• 2(-5)= -10

2) Next you want to take the -10 and plug it into the equation for h(x)

• (-10)²+4= 104
