Based on a poll of 1000 residents, a newspaper article claims that 62% of the residents in town favor the development of a recreational
park on the west side of town. A community action group interested in preserving the environment claims that 45% of the town's
residents favor the development of a recreational park.
To determine whether the sample supports the
population proportion, a simulation of 100 trials is run, each with a
sample of 200, using the point estimate of the population. The minimum sample proportion from the simulation is 0.46 and the
maximum sample proportion is 0.76.
What is the point estimate of the population?
The margin of error of the population proportion is found using an estimate of the standard deviation. What is the
interval estimate of the true population proportion?
The margin of error of the population proportion is found using the half the range.
What is the interval estimate of the true population proportion?
Is the community action group's claim likely based on either interval estimate of the true population proportion?
Explain.

Answers

Answer 1

The probability computed shows that the point estimate of the population is 6.2%.

How to calculate the probability?

Divide the number of events by the number of possible outcomes. After determining the probability event and its corresponding outcomes, divide the total number of ways the event can occur by the total number of possible outcomes.

a. The point estimate of the population will be calculated thus:

= 62% = 62/100 = 0.62

b. The margin of error of the population will be:

= z value × [✓0.62 × ✓0.38 / ✓200]

= 1.96 × (0.78 × 0.61 / 14.14)

= 0.0672

Therefore, the interval estimate is 6.72%.

c. The margin of error of the population proportion is found using half the range will be:

= [0.76 - 0.46] /2

= 0.30/2

= 0.15

d.  The community action group’s claim is likely based on either interval estimate of the true population proportion since the confidence interval value is greater than 0.45.

(b)

[tex]\sum\limits^n_1 { 3(-4)^{n-1}[/tex]

Step-by-step explanation:

Given

The above sequence

Solving (a): The explicit formula

The given sequence is a geometric sequence because the common ratio (r) is:

[tex]r = \frac{-12}{3} = \frac{48}{-12} = \frac{-192}{48} = \frac{768}{-192}[/tex]

[tex]r = -4[/tex]

The explicit formula is calculated using the n term of an GP.

[tex]T_n = ar^{n-1}[/tex]

[tex]T_n = 3 * (-4)^{n-1}[/tex]

[tex]T_n = 3(-4)^{n-1}[/tex]

Solving (b): Summation notation.

This implies that the sum of the sequence.

To do this, we write Tn inside the summation sign

Substitute values for Tn

We are told that the costs add up this way:

  trip cost = bus rental + 2 × (cost of play)

Given that ...

trip cost = $65bus rental = $10cost of play = x

The above equation can be rewritten as ...

Step-by-step explanation:

Given

[tex]\angle A = 10[/tex]

[tex]\angle B = 145[/tex]

Required

Similar [tex]\triangle[/tex] to [tex]\triangle ABC[/tex]

The question is incomplete as the other triangles to make comparison from, are not given.

However, general information that could help you are as follows.

The given parameters show that we have to consider AA criterion for selecting similar triangles.

So, you need to check the [missing] given triangles, and pick any that have 10 and 145 (in that particular order) as measures of two of its angles.

Take for instance.

[tex]\triangle DE\ F[/tex]

Where

[tex]\angle D = 10[/tex]

[tex]\angle E = 145[/tex]

See that:

[tex]\angle D = 10[/tex] is similar to [tex]\angle A = 10[/tex]

Compound X is made up of two parts A and one part B. The mass of compound X is 45, and A has twice the mass of B. Which two equations would you solve to find the individual masses of A and B?

Answers

Answer:

[tex]A = 2B[/tex]

[tex]A + B = 25[/tex]

Step-by-step explanation:

Given

The first statement implies that:

[tex]X = A + B[/tex] i.e the components of X

Reading further, we have:

[tex]X = 45[/tex] ---- The mass of X

[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]

Required

Two equations to represent the scenario

The two equations are:

[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]

[tex]X = A + B[/tex] i.e the components of X

Substitute 25 for X in the second equation

[tex]25 = A + B[/tex]

[tex]A + B = 25[/tex]

So, the equations are:

[tex]A = 2B[/tex]

[tex]A + B = 25[/tex]

3.What is ratio. ​

Answers

Answer:

answer is 90 hr for question 1

Step-by-step explanation

48 hr     8 liter

 ?           15 liter

so what ur going to do is u criss-cross when u do u multipy 48 with 15 and 8 with "?" when u multiply 48 with 15 u get 720 and when you multiply 8 with "?" u get 8?

so it will look like this

720= 8?

let make "?" an "x" for a better understanding. so the reason we are making it an "x" is because we dont know the amount of hr it takes for 15 liters of water to leak.

let go back to the calculation.

so it will look something like this

720 = 8x

exactly the same thing but we made "?" an"x"

so now we divide both sides with 8. why? because we need "x" alone and want 8 to disappear

so when u divide both sides with 8 it will look something like this

780/8 =x

so when u divide 780 with 8 u get 90. so what does that mean? it means it takes 90 hr for 15 liters of water to leak.

do you understand?

The number of seats in a row is found by dividing seats by rows.

In 18 rows

  450 seats/(18 rows) = 25 seats/row

In 15 rows

  450 seats/(15 rows) = 30 seats/row
