False. Randomization distributions are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.

Randomization distributions are generated through permutation tests, which involve random shuffling of data points between groups. In hypothesis testing, the null hypothesis assumes that there is no difference between groups or no effect of a treatment. The alternative hypothesis suggests otherwise.

The randomization distribution is created by repeatedly shuffling the data and calculating a test statistic based on the null hypothesis. This distribution represents the expected outcomes if the null hypothesis is true. Therefore, the randomization distributions are centered at the value where the null is false, as they capture the potential differences or effects between groups.

In summary, randomization distributions are not centered at the value where the null is true; rather, they are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.

The product of the algebraic expression as the product of (2p + q) and (-3q - 6p + 1) is; - 12p² - 12pq + 2p - 3q²+ q

We want to find the product of (2p + q) and (-3q - 6p + 1) and this gives;

(2p + q) * (-3q - 6p + 1)

Now, this can be broken down further using distributive property of algebra into;

2p(-3q - 6p + 1) + q(-3q - 6p + 1)

= -6pq - 12p² + 2p - 3q² - 6pq + q

We can be 99.7% confident that the true proportion of individuals with schizophrenia in the population lies between 0.44 and 0.62.

In our schizophrenia model, the rough 99.7% certainty stretch can be determined utilizing the point gauge and standard blunder of the extent. With a point gauge of 0.53 and a standard blunder of 0.03, we can involve the equation for a certainty stretch, which is point gauge ± z* (standard mistake), where z* is the z-score related with the ideal certainty level.

For a 99.7% certainty stretch, the z-score is roughly 3. Consequently, the certainty span would be:

0.53 ± 3(0.03) = (0.44, 0.62)

This implies that we can be 99.7% certain that the genuine extent of people with schizophrenia in the populace lies somewhere in the range of 0.44 and 0.62.

To find the equation for the plane through the point p0=(7,7,3) and normal to the vector n=6i+2j+7k, we can use the formula for the equation of a plane which is Ax + By + Cz = D.

The equation of the plane through the point p0=(7,7,3) and normal to the vector n=6i+2j+7k is:
6x + 2y + 7z = 77

This is further explained as follows:

The equation of a plane is given by:
Ax + By + Cz = D
where A, B, and C are the components of the normal vector, and D is a constant. To find A, B, and C, we can use the components of the given normal vector n=6i+2j+7k.

Therefore we have:
A = 6, B = 2, C = 7
Now, substitute the values of A, B, and C into the equation:
6x + 2y + 7z = D

To find the value of D, we can substitute the coordinates of the given point p0=(7,7,3) into the equation and solve for D. So, we have:
6(7) + 2(7) + 7(3) = D
42 + 14 + 21 = D
D = 77

A sketch with dimension 2 inches by 6.9 inches has the closest ratio to the actual billboard.

In this question we have been given that an ad campaign manager for McDonalds made some sketches for a billboard design on a sheet of paper. The actual board is 14 feet by 48 feet.

we need to select the measurement that has the closest ratio to the actual billboard.

The dimensions of the actual billboard:

length = 48 feet

width = 14 feet

The length to width ratio is:

48/14 = 3.43

Now we find the ratio of length and width for each given dimension of the sketch.

1) 8 inches by 11 inches

r1 = 11/8

r1 = 1.375

2) 1.7 inches by 9.2 inches

r2 = 9.2/1.7

r2 = 5.41

3) 2 inches by 6.9 inches

r3 = 6.9/2

r3 = 3.45

Step-by-step explanation:

The brightness of the Sun as viewed from a distance of 10 AU compared to its brightness on Earth can be determined using the inverse square law. The Sun would appear approximately 1/100th (or 0.01) as bright as it appears from Earth at this distance.

The inverse square law states that the brightness of a light source decreases as the square of the distance from the source increases. In this case, we are comparing the brightness of the Sun on Earth to its brightness when viewed from a distance of 10 AU (astronomical units). Since AU is a unit of distance used to measure distances within the solar system, 1 AU represents the average distance between the Earth and the Sun, approximately 93 million miles or 150 million kilometers.

Using the inverse square law, we can calculate the relative brightness. If we consider the distance from the Sun on Earth as d1 and the distance from the Sun at 10 AU as d2, the brightness ratio (B(d2)/B(d1)) is equal to (d1/d2)^2. Substituting the values, we find that the Sun would appear approximately 1/100th (or 0.01) as bright when viewed from a distance of 10 AU compared to its brightness on Earth. Therefore, the Sun would appear significantly dimmer when observed from such a distance in the solar system.

The inequality best representing the trial numbers in which Hannah feels 2 points is t > 7.

In the question, we are given that Arianna and Hannah are conducting an experiment to test the difference threshold for sense of touch on the forehead. For trial 1, Hannah closes her eyes while Arianna gently touches 2 paperclip points 3 millimeters (mm) apart on Hannah's forehead. Then Hannah reports whether she could feel 1 or 2 points. For each of the next trials, Arianna and Hannah repeat this process, each time with the points 2 more mm apart. Hannah reports feeling 1 point until the points are 15mm apart, when she begins reporting that she feels 2 points.

We are asked for the inequality that best represents the trial numbers in which Hannah feels 2 points.

We know that for trial 1, the paperclip points are 3 mm away.

After that the gap between the paperclips are exceeded by 2 mm.

Thus, for trials:

2 we have paperclips at 5 mm gap.

3 we have paperclips at 7 mm gap.

4 we have paperclips at 9 mm gap.

5 we have paperclips at 11 mm gap.

6 we have paperclips at 13 mm gap.

7 we have paperclips at 15 mm gap.

8 we have paperclips at 17 mm gap.

9 we have paperclips at 19 mm gap.

and so on.

We are informed that until the gap is 15 mm, she reports 1 points and after that she reports 2 points.

15 mm is for trial 7.

Thus, after 7th trial, she reports 2 points.

a. t > 6

b. t < 6

c. t < 7

d. t > 7"

Answer: The inequality best represents the trial numbers in which Hannah feels 2 points is t>7

Step-by-step explanation:

Given: Ariana and Hannah are conducting an experiment to test the difference threshold for sense of touch on forehead.

Initially, the 2 paperclips are 3 mm apart on Hannah’s forehead.

To be more clear about the two points where the paperclips are touched on Hannah’s forehead, let us assume circle C to be Hannah’s forehead and A and B are the two points (as shown in the image).

Hannah feels only 1 point

For trail 1, the paperclips are 3mm apart.

Given, for each next trail, the gap is increased by 2mm.

So, for trail 2, the gap (Distance between 2 points A and B) is 3mm + 2mm = 5mm.

For trail 3, gap is 5mm + 2mm = 7mm

For trail 4, gap is 7mm + 2mm = 9mm

For trail 5, gap is 9mm + 2mm = 11mm

For trail 6, gap is 11mm + 2mm = 13mm

For trail 7, gap is 13mm + 2mm = 15mm

And so on.

According to the question, for a distance greater than 15mm, Hannah starts reporting that she is feeling two points.

Thus, till the 7th trail, Hannah reports 1 point on her forehead and after it she reports 2 points.

Hence,

The inequality best represents the trial numbers in which Hannah feels 2 points is t>7 (where t is the trial number).

The unit rate is 3/2, which means the person is traveling at a rate of 3/2 miles per hour.

To find the unit rate, divide the distance traveled (in this case, 3/4 miles) by the time taken (in this case, 1/2 hour).

(3/4 miles) ÷ (1/2 hour)

To divide fractions, multiply the numerator of the first fraction by the reciprocal of the second fraction:

(3/4 miles) × (2/1 hour)

Multiplying the numerators and denominators, we get:

(3 × 2) / (4 × 1) = 6/4

Next, simplify the fraction:

6/4 simplifies to 3/2

Therefore, the unit rate is 3/2, which means the person is traveling at a rate of 3/2 miles per hour.
