A large t-statistic indicates a greater difference between the sample means and provides stronger evidence for a significant difference between the populations.

The t-statistic is a measure of the difference between two sample means relative to the variability within the samples. When the population means are different, the difference between the sample means will tend to be larger, which will result in a larger numerator in the t-statistic formula. The larger the difference between the sample means, the greater the evidence for a difference between the populations. In contrast, if the population means are similar, the difference between the sample means will be smaller, resulting in a smaller numerator and a weaker test of significance.

The denominator of the t-statistic formula is the standard error of the mean, which measures the variability of sample means around the population mean. If the sample size is large enough, the standard error of the mean will be small, resulting in a smaller denominator and a larger t-statistic. Therefore, when the population means are different, a larger t-statistic would be expected due to a combination of a larger numerator and a smaller denominator.

In summary, If the population means are different, a large t-statistic would be expected.

Answer:

If you meant the area was 255 in²:

Perimeter is \(4\sqrt{255}\), or around 63.89 in.

If you meant that the area was 225 in²:

Perimeter is 60 in

Step-by-step explanation:

If you meant the area was 255 in²:

If we have a square with an area of 255 in², then it's side length will be \(\sqrt{255}\) inches long, since the area of a square is \(l^2\), where l is the length.

Since \(\sqrt{255}\) doesn't return a rational number, we'll leave it as \(\sqrt{255}\).

Now that we know the side length, the perimeter of a square is represented as \(4l\), where l is the length.

We know the length is \(\sqrt{255}\), so we can multiply this by 4.

\(4\sqrt{255}\). This is the simplest it gets.

If you meant the area was 225 in²:

Following the same concept as again:

Length: \(\sqrt{225} = 15\)

Perimeter: \(4\cdot15=60\) in

Hope this helped!

Answer:

P = 63.87 in

Step-by-step explanation:

area of a square window = 255 in²

find perimeter of the window.

A = s²

255 = s²

s = 15.97 in.

perimeter = 4 * s

P = 4 (15.97)

P = 63.87 in

Answer:

you just multiply.. you take a number and times it by another

Step-by-step explanation:

The probability of the complement of the intersection of events A and B is 0.9 or 90%.

Given:

P(A) = 0.3

P(B) = 0.4

P(A∩B) = 0.1

To calculate P[(A∩B)c], we'll first find P(A∩B) using the formula:

P(A∩B) = P(A) + P(B) - P(A∪B)

P(A∪B) = P(A) + P(B) - P(A∩B)

P(A∪B) = 0.3 + 0.4 - 0.1

P(A∪B) = 0.6

Now, we can find P[(A∩B)c] by subtracting P(A∩B) from 1:

P[(A∩B)c] = 1 - P(A∩B)

P[(A∩B)c] = 1 - 0.1

P[(A∩B)c] = 0.9

Therefore, the probability of the complement of the intersection of events A and B is 0.9 or 90%.

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Step-by-step explanation:

Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

 Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

 book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

 to read after x days

∴ y = 450 - 30 x

The linear equation is y = 450 - 30 x, where y is the number of

pages Lourdes has left to read after x days

Step-by-step explanation:

Look at it upside down!

18.75 inches is the length of the rectangle and 18.75 inches is the width of rectangle.

The area of Rectangle is length times of width.

The perimeter of a rectangle is 50 inches.

Perimeter=2(Length+Width)

Length=3W

Perimeter=50 inches

50=2(3W+W)

50=2(4W)

50=8W

Divide both sides by 8

50/8=W

W=6.25

Length=3(6.25)=18.75.

Hence, the length of rectangle is 18.75 inches and width is 6.25 inches.

If a large airline wants to estimate its average number of unoccupied seats per flight over the past year Then a 92% confidence interval for the population mean number of unoccupied seats per flight is (10.334, 12.266) seats.

To construct a confidence interval for the population mean number of unoccupied seats per flight, we will use the following formula CI = X ± z*(σ/√n)

Where:

X = sample mean = 11.3 seats

σ = sample standard deviation = 4.3 seats

n = sample size = 300

z = z-score corresponding to the desired confidence level of 92%, which we can look up in a standard normal distribution table or use a calculator. For a 92% confidence level, the z-score is 1.75.

Plugging in the values, we get:

CI = 11.3 ± 1.75*(4.3/√300)

CI = 11.3 ± 0.966

Therefore, the 92% confidence interval for the population mean number of unoccupied seats per flight is (10.334, 12.266) seats. This means we can be 92% confident that the true population means a number of unoccupied seats per flight falls within this interval.

The size class interval recommend is 30.

Assume that the observations are more or less evenly distributed across the range, and you should get about 5 observations per class.

It also presumes that your interest in the observations is uniform: you are equally interested in values close to 60 as you are in values close to 480. If you were only interested in values above 450, you could group all values from 56 to 449 into one large class and divide the rest into smaller classes.

It is also necessary to check to see if the distribution is uniform. If it is skewed in either direction, it makes more sense to have smaller classes where the observations are dense and larger classes where they are sparse.

1/4 of 168 is 42 which is how many Boxes of Candy they sold

42 x 1.50 = 63

Answer:

From the sale of boxes of candy, the team made $63

Explanation:

We know that 3/4 of the sold items were chocolate bars. A fast trick to find 3/4ths, or 75%, of a number is to multiply it by 3 and divide by 4.

168 * 3 = 504

504 ÷ 4 = 126

Now, we do 168 - 126 to find the number of candy boxes.

168 - 126 = 42

So, the soccer team sold 42 boxes of candy. Since each box was $1.50, we just multiply

42 * 1.50 = 63

The soccer team made $63 dollars by selling candy boxes.
