Which statistic is used to determine if there is a significant difference between three or more sets of related scores

1 answer:

7 0

The t-test is a type of inference statistic used to determine if there is a significant difference between the means of two groups that may be related to a particular characteristic. The t-test is one of many tests used to test statistical hypotheses.

Inference statistics have two main purposes. Estimates for population groups (for example, the average SAT score for all 11th graders in the United States). Hypothesis testing to draw inferences about the population

One-way ANOVA is a common method for comparing three or more group means. The usual goal is to determine if the mean (or median) of at least one group is different from the other. Subsequent multiple comparison tests are often used to determine where differences occur.

Maksim231197 [3]

Given:

The statement is "two sevenths times four sixths".

To find:

The value of the product.

Solution:

Two sevenths times four sixths can be written as:

$\dfrac{2}{7}\times \dfrac{4}{6}$

It can be rewritten as:

$\dfrac{2}{7}\times \dfrac{4}{6}=\dfrac{2\times 4}{7\times 6}$

$\dfrac{2}{7}\times \dfrac{4}{6}=\dfrac{8}{42}$

The answer of given expression is eight forty seconds.

Therefore, the correct option is B.

Lynn is a single mother with two children's . She qualifies to file as head of household her total income was $27267 last year h

storchak [24]

Answer:

$3,078.04

Step-by-step explanation:

-Given her income is $27,267, she falls under the 10% and 12% brackets with the following boundaries as attached.

-Her tax is then calculated as;

#10% bracket;

$Tax=Taxable \ Income \times Tax \ Rate\\\\=9700\times 10\%\\\\\\=\$970.00$

#12% Tax bracket:

$Tax=Taxable \ Income \times Tax \ Rate\\\\=(27267-9700)\times 12\%\\\\\\=\$2108.04$

The total tax=970+2108.04=$3,078.04

Hence, Lynn owes $3,078.04 in taxes.

What are all of the factors of 24 and 27

klasskru [66]

The factors of a number are all of the positive whole numbers that go into it evenly. For example, 2 is a factor of 6 because 6 ÷ 2 = 3, or equivalently, 6 = 2 x 3. Note that this naturally implies that every whole number has 1 and itself as a factor.

The numbers that go evenly into 24 are 1, 2, 3, 4, 6, 8, 12, and 24. For 27, those numbers are 1, 3, 9, and 27.

The common factors between two numbers are numbers that go into both numbers evenly. Looking through the lists for 24 and 27, we see that 1 and 3 are their common factors. The greatest common factor is, of course, the largest of these, so the greatest common factor of 24 and 27 is 3.
