Answer:

A two-tailed test.

Step-by-step explanation:

ANOVA is a short term or an acronym for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.

Basically, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the mean of two or more populations are equal through the use of null hypothesis or a F-test.

Hence, the null hypothesis for an analysis of variance (ANOVA) requires that all treatments or samples should be generated from populations having the same mean.

A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called a two-tailed test.

Eva wants to estimate the number of rabbits on a farm.
user100 [1]

Estimate the number of rabbits on the farm will be 417 rabbits.

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Eva wants to estimate the number of rabbits on a farm.

On Monday, she catches 50 rabbits.

These rabbits are tagged and then released.

On Tuesday, she catches 100 rabbits.

12 of these rabbits have tags on them.

Then estimate the number of rabbits on the farm that will be

Let n be the number of total rabbits. Then we have

12n = 50 x 100

  n = 5000 / 12

  n = 416.67

  n ≅ 417

The solutions of the system of equations are (0 , 13) , (3 , 34)

Step-by-step explanation:

To solve an system of equations, one of them linear and the other is quadratic do that

  • Use the linear equation to find one variable in terms of the other variable
  • Substitute this variable in the quadratic equation
  • Solve the quadratic equation to find the values of the other variable
  • Substitute the values of the other variable in the linear equation to find the first variable

The system of equation is:

y = x² + 4x + 13 ⇒ (1)

y = 7x + 13 ⇒ (2)

Substitute y in equation (1) by equation (2)

x² + 4x + 13 = 7x + 13

Subtract 13 from both sides

∴ x² + 4x = 7x

Subtract 7x from both sides

x² - 3x = 0

Take x as a common factor

x(x - 3) = 0

Equate each factor by 0

x = 0

x - 3 = 0

Add 3 to both sides

x = 3

The values of x are 0 and 3

Substitute the values of x in equation (2) to find y

When x = 0

y = 7(0) + 13

y = 0 + 13

y = 13

When x = 3

y = 7(3) + 13

y = 21 + 13

y = 34

The values of y are 13 and 34

The solutions of the system of equations are (0 , 13) , (3 , 34)
