The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16 hours.

In this case, we are estimating the difference in population means between two groups - upperclassmen and underclassmen. The point estimate is calculated by subtracting the sample mean of the underclassmen from the sample mean of the upperclassmen, which gives us

0.76 - 0.60 = 0.16.
the point estimate of the difference in population mean exercised between underclassmen and upperclassmen is 0.16 hours, which was calculated by subtracting the sample mean of underclassmen from the sample mean of upperclassmen.
Point Estimate = (Sample Mean of Upperclassmen) - (Sample Mean of Underclassmen)
Point Estimate = (0.76) - (0.60)
Point Estimate = 0.16

Hence, the point estimate of 0.16 suggests that, on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours. This is a rough estimate of the difference between the two population means based on the provided sample data.

The endpoints of a segment are M(2,5) and N(8,-1). What are the new endpoints of it if it is translated along the vector <-2,3>

Answer:

\(M_n(0,8) \\N_n(6,2)\)

Step-by-step explanation:

From the question we are told that

\(Point1= M(2,5)\\Point1= N(8,-1)\)

Generally the translation along the vector <-2,3> is mathematically given as

\(map(x,y)=(x-2,y+3)\)

Therefore

\(M(2,5)=(2-(2,5+3))\\M(2,5)=(0,8)\)

\(N(8,-1)=((8-2)(-1+3))\\N(8,-1)=((6,2)\)

Generally  the new endpoints are are mathematically given

\(M_n(0,8) \\N_n(6,2)\)

the correct answer is a. likely to be due to true differences between the groups.

If we say we have statistically significant results, it means that the results are likely to be due to true differences between the groups. Statistical significance is a term used in hypothesis testing to determine if the observed differences between groups are likely to be real and not due to chance.

When conducting a statistical analysis, researchers compare the data from different groups or samples to see if there is a significant difference between them. This involves calculating a p-value, which represents the probability of obtaining the observed results if there were no true differences between the groups.

If the p-value is less than a predetermined threshold, typically 0.05, then the results are considered statistically significant. This means that the likelihood of obtaining the observed results by chance alone is very low, and it is more likely that the differences between the groups are due to a real effect.

For example, let's say we conduct a study to compare the effectiveness of two different treatments for a medical condition. If we find that the p-value is less than 0.05, we can conclude that there is a statistically significant difference between the treatments, and the observed improvement in one group is likely to be due to the treatment itself rather than random chance.

In summary, when we say we have statistically significant results, it means that the observed differences between groups are likely to be due to true differences rather than chance. This provides evidence for the presence of a real effect or relationship between the variables being studied.

Step-by-step explanation:

Answer:

There are 120 students in the choir.

Step-by-step explanation:

Given that:

Number of members who participated in contest = 36

This represents 30% of the total members of choir at the school.

Let,

x be the number of total sutdents

30% of x = 36

\(\frac{30}{100}x=36\)

0.3x = 36

Dividing both sides by 0.3

\(\frac{0.3x}{0.3}=\frac{36}{0.3}\\x=120\)

Hence,

There are 120 students in the choir.

To find the image of point P(-2,-2) translated 1 unit to the left and 3 units down, we subtract 1 from the x-coordinate and 3 from the y-coordinate to get coordinates of P' as: (-3, -5).

To translate a point to the left, we subtract from its x-coordinate, and to translate it down, we subtract from its y-coordinate.

Therefore, to translate P(-2, -2) 1 unit to the left and 3 units down, we subtract 1 from the x-coordinate and 3 from the y-coordinate to get P'(-3, -5) as the image of P after translation.

Therefore, the coordinates of P' are (-3, -5).

Answer:

x = 120

Step-by-step explanation:

A regular polygon means all sides and angles are equal.  If a triangle has 180 degrees total, 180 / 3 = 60.  That means each angle is 60 (interior angle).  That is a straight line, which is 180 degrees, 180 - 60 = 120.  

The population in 2026 according to the exponential growth function will be approximately 54,515.

Given,

The population in 2001 = 26,100

Annual growth rate = 4%

Population growth function can be written as,

\(P(t) = P0e^rt\)

Where,P(t) = Population after t years

P0 = Population at time t = 0

r = Annual growth rate (in decimal form)

t = Time (in years)

According to the given question,In the year 2026, the number of years from 2001 is,2026 – 2001 = 25 years

Therefore,t = 25 years

r = 4% = 0.04

Using these values in the population growth function,

\(P(t) = P0e^rt\)

Population in 2026 = P(25)

\(P(25) = 26,100e^(0.04 x 25)\)

P(25) = 26,100e

P(25) ≈ 54,515

We have the next information

A submarine Is at a depth of 350 feet below sea level means -350

First, it goes down 150 feet. means -150

Next, it goes up 132 feet. means +132

Then, it goes down 179 feet. means -179

Finally, it goes down 145 feet means -145

then we have the next operations

-350+(-150)+132+(-179)+(-145)=-692

The sing minus means that It is below the sea level

therefore the correct choice is

A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.

The length of the rectangle is (10+x) cm and the width of the rectangle is x cm.

According to the question,

We have the following information:

The width of the rectangle = x cm

Now, the length of the rectangle is given to be 10 cm more than the width of the rectangle.

So, this can be converted in the following mathematical expression:

Length of the rectangle = 10+x cm

(More to know: the area of the rectangle is given by the formula l*b where l is the length and b is the breadth of width of the rectangle.)

The correct answer is b. Each block should consist of volunteers who live in similar environments when it comes to mosquitoes.

Explanation:

In a randomized block design, blocks are formed to control for potential confounding factors or sources of variation that may affect the outcome of the experiment. By forming blocks based on similar environments when it comes to mosquitoes, the researchers ensure that any differences in the effectiveness of the bracelet and bug spray are not solely due to variations in mosquito exposure.

If the researchers were to choose option a (both the volunteers and researchers should be kept blind as to which block the volunteers are in), it would be related to blinding the participants and researchers to the treatment assignment, not forming blocks. This method does not address the need for controlling potential confounding factors.

Option c (each block should consist of volunteers who live in different environments when it comes to mosquitoes) would not be suitable because it would introduce additional variability and make it difficult to compare the effectiveness of the bracelet and bug spray.

Option d (each volunteer should be randomly assigned to a block) is not recommended in this case because it does not take into account potential confounding factors related to mosquito exposure.

Option e (volunteers in one block should use the bracelet, while volunteers in the other block should use bug spray) does not control for potential confounding factors, as individuals in different blocks may have different levels of mosquito exposure.

Step-by-step explanation:

Answer:

y = 5/12 x + 2

Step-by-step explanation:

We need to find the equation of a line that passes through two given points.

y = mx + b

First, we find the slope.

m = slope = (y2 - y1)/(x2 - x1)

m = (7 - 2)/(12 - 0) = 5/12

Now we have

y = 5/12 x + b

To find the value of b, we use a point for x and y and solve for b.

y = (5/12)x + b

2 = (5/12)(0) + b

b = 2

The equation is

y = 5/12 x + 2
