A magazine provided results from a poll of 2000 adults who were asked to identify their favorite pie.

Given specific sample data, which confidence interval is wider the 95% confidence interval interval? Why is it wider? r the 80% confidence Choose the correct answer below A. An 80% confidence interval must be wider than a 95% confidence interval in order to be more confident that it captures the true value of the population proportion. B. A 95% confidence interval must be wider than an 80% confidence interval because it contains 95% of the true population parameters, while the 80% confidence interval only contains 80% of the true population parameters B. C. An 80% confidence interval must be wider thant> 95% confidence interval because it contains pr 100%-80%-20% of the true population parameters, while the 95% confidence interval only contains 100%-95%-5% of the true population parameters. D. A 95% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the population proportion. D.

Answers

Answer 1

The correct answer is D. A 95% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the population proportion.

The width of a confidence interval reflects the degree of uncertainty about the estimate of the population parameter. A wider interval indicates a higher degree of uncertainty, while a narrower interval indicates a lower degree of uncertainty.

The confidence level of a confidence interval is the probability that the interval contains the true population parameter. For example, a 95% confidence interval means that there is a 95% probability that the interval contains the true population parameter. Similarly, an 80% confidence interval means that there is an 80% probability that the interval contains the true population parameter

Since a 95% confidence interval is more confident that it captures the true value of the population parameter than an 80% confidence interval, the 95% confidence interval must be wider in order to capture the true value with a higher degree of confidence.

what is angle 1 im marking brailiest

Answers

Answer:

86

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

1. The other angle marked with one arc must also be 43 deg.

2. The two angles put together make an angle of 86 deg.

3. In a parallelogram, the angle at lower right and the angle at upper right are supplementary (they add up to 180 deg.). The upper right angle is 180 - 86 = 94 deg.

4. The angle at lower left is the same, 94 deg.

5. The angles marked with two arcs are half of 94 deg. = 47 deg.

6. Now you have two out of three angles in the triangle. All three angles add up to 180 deg. so the measure of angle 1 is 180 - 47 - 43 = 90 degrees.

At his birthday party, Aiden collected 15% of the candy that fell out of the piñata. If Aiden collected 6 pieces of candy, how many pieces of candy fell out of the piñata?

Answers

Answer:

40 pieces

Step-by-step explanation:

To make it easier, I'm gonna divide 15 by 3 and then multiply it by 2. Same with 6.

10% of candy = 4 pieces.

Multiply by 10

100% of candy = 40 pieces.

A recent earthquake in Peru registered a 4.0 on the Richter scale. How much energy in ergs was released by this earthquake?
(Enter you answer in terms of 10 and use Shift 6^ for exponents)
ergs

Answers

Answer:

10¹⁸ ergs

Step-by-step explanation:

From the question,

Using the expression

M = [tex]\frac{4}{5}[/tex]log(E/10¹³)................. Equation 1

Where M = Richter magnitude of earth quake, E = Energy released in ergs.

Given: M = 4.0

Substitute into equation 1 amd solve for E

4 = [tex]\frac{4}{5}[/tex]log(E/10¹³)

Log(E/10¹³) = (4×5)/4

Log(E/10¹³) = 5

E/10¹³ = 10⁵

E = 10⁵×10¹³

E = 10⁵⁺¹³

E = 10¹⁸ ergs

v=3.2

Step-by-step explanation:

Let's solve your equation step-by-step.

−12.3+7v=10.1

Step 1: Simplify both sides of the equation.

7v−12.3=10.1

Step 2: Add 12.3 to both sides.

7v−12.3+12.3=10.1+12.3

7v=22.4

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

[tex]y = (x - 5)(5x + 4) - 5x^2[/tex]

First we have to simplify y, before solving the question:

[tex]y = (x - 5)(5x + 4) - 5x[/tex]

Applying the distributive property:

[tex]y = 5x^2 + 4x - 25x - 20 - 5x^2[/tex]

[tex]y = 0x^2 - 21x - 20[/tex]

[tex]y = -21x - 20[/tex]

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

c. A two-sample z-test for a difference between proportions
d. A linear regression t-test for slope
e. A matched pairs t-test for a mean difference

Answers

Answer:

e. A matched pairs t-test for a mean difference

Step-by-step explanation:

When the observations from two samples are paired either naturally or by design we find the differences between the two observations of each pair.Treating the differences as a random sample from a normal population with mean ud= u1-u2 and unknwn standard deviation σd we perform one sample t- test on them. This is called the paired difference t- test or a paired t- test.

Suppose 10 young recruits are given a physical training by the Army . Their weights are recorded before and after the training. These observations constitutes natural pairing .

When we eliminate the undesireable sources of variation to take observations in pairs , this is called pairing by design.

With the values given

[tex]P(-5 \leq x \leq 5) = P(x = -5) + P(x = 0) + P(x = 5) = 0.15 + 0.05 + 0.1 = 0.3[/tex]

Answer:

y = x

Step-by-step explanation:

Hi,

We know that in the equation...

y = mx + b

m = slope

So, to find the equation of the line, we have to plug in what we already know. So...

-7 = 1 (-7) + b

Solve...

-7 = -7 + b

b = 0

That means that your equation is...

y = x

(you don't have to put the one in front of the x)

I hope this helps :)

y = mx + b
The m represents your slope.
y = (1)x + b
You can now plug in your coordinate points.
-7 = -7 + b
You will notice that they are equal to each other, which means b can only equal zero.
The equation will be...
y = x + 0
or
y = x
