Eva8 [605]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Upper level seat = $25

Mid level seat = $40

Number of tickets to give away is at least 25

Budget constraint = $1000

part A: write a system of two inequalities that describe this situation

Number of tickets constraint:

Upper level + mid level ≥ 25

u + m ≥ 25

Cost constraint :

$25u + $40m ≤ $1000

Part B:

Give away 10 upper level seat tickets and 15 mid level seat tickets

A local service agency hires you to estimate the average annual income of all 700 families living in a four square block section

Digiron [165]

Answer:

The true estimate of the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval below

$34854.3 < \mu < 35 745.7$

Step-by-step explanation:

From the question we are told that

The sample size is n = 50

The sample mean is $\= x = \$ 35300$

The population standard deviation is $\sigma = \$ 1800$

From the question we are told the confidence level is 92% , hence the level of significance is

$\alpha = (100 - 92 ) \%$

=> $\alpha = 0.08$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.751$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.751 * \frac{1800 }{\sqrt{50} }$

=> $E = 445.7$

Generally 92% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $35 300 -445.7 < \mu < 35 300 + 445.7$

=> $34854.3 < \mu < 35 745.7$

So the true estimate of the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval
