in hypothesis testing, type ii error occurs when: group of answer choices you reject the null hypothesis when the null hypothesis is true you fail to reject the null hypothesis when the null hypothesis is false you reject the null hypothesis when the null hypothesis is false you fail to reject the null hypothesis when the null hypothesis is true
A Type I error occurs in hypothesis testing when one is rejects the null hypothesis and the null hypothesis is true.
To reject the null hypothesis, statisticians conduct hypothesis testing. However, the process is always accompanied by the possibility of making a mistake. These are referred to as hypothesis testing errors.
Type I and Type II errors are the two mutually exclusive errors in hypothesis testing. Type II errors occur when a statistician fails to reject a false null hypothesis, whereas Type I errors occur when a statistician correctly rejects a genuine null hypothesis. So, c is the right response.

The average income of those who work more and those who work less tends to be equal
What is the null hypothesis?The null hypothesis is a typical statical theory which suggest that no statical relationship and significance exists in a set of given single observed variable , between two sets of observed data and measured phenomena.
The null hypothesis is significant because it offers a rough description of the phenomena inferred from the available evidence. It enables researchers to empirically test the relationship statement in a study.
Example: The null hypothesis is that the population density is the same across all states.

Using the inverse operations, the value of h is 54.
How to use inverse operation to solve equation?An inverse operation can be defined as the operation that undoes what was done by the previous operation.
Therefore, the inverse operation of multiplication is division.
The equation is as follows:
19 = (h/3) - 8
Hence,
add 8 to both sides of the equation
19 = (h/3) - 8
19 + 8 = (h/3) - 8 + 8
27 = h / 3
Multiply both sides of the equation by 3
27 = h / 3
27 × 3 = h / 3 × 3

Identify the domain and range of the function in interval notation. Find the zeros of the function. Then determine for which values of x the function is positive and for which it is negative
Answer:
Domain: (-5, ∞)
Range: [-4, 1]
Step-by-step explanation:
Domain is the set of all permissible values of x for the function. The smallest value of x is at x = -5. However note that there is an unfilled circle at x = -5 where y = -1. This means the point(-5, -1) is excluded in the function
The function flattens out at x = 3 and the arrow on the end of the function plot indicates that the x-value of the function goes up to ∞
The domain in interval form is (-5, ∞).
Be careful with the brackets. The regular parentheses ( and ) indicate that the extremes of the interval -5 and ∞ are not included in the interval. ∞ is never included. Such an interval is called an open interval.
The range is the set of y-values for the domain
Looking at the graph we can see that the lowest y value is -4 at x = -2 and it is a valid value for the function so included in the interval
The highest value of y is 1 and it becomes 1 at x =3 but since the plot after x = 2 is horizontal, that means the y value will be 1 for any value x >= 3
Therefore the range of the function is
[-4, 1]
Here note that we are using square brackets to indicate that -4 and 1 are included in the interval. Such an interval is called a closed interval.

If Emily wants to buy a 22 feet wire and Andy wants to buy a 14 yards wire then their total cost would be $23.04.
What is feet and yard?The length of a foot is 12 inches. A ruler can be used to calculate the length of a foot, which is usually one foot. The length of a piece of paper is about one foot.
3 feet make up one yard. A yardstick, which is equal to 1 yard, is typically used to measure yards. The length of a baseball bat is about one yard.
Using the conversion Rule we will convert feet into inches that is
22 feet = 264 inches
We will also convert yards into inches that is
14 yards = 504 inches
Total wire they need = 264 + 504 inches
= 768 inches
We have given that
100 inches wires costs = $3
1 inch wire costs = 3/100
768 inch wire costs = (3/100) × 768

What is the congruence property?When two objects or figures have the same size and shape, the term "congruence" is used to describe it. Congruence has the transitive property, which states that if two sets of lines, angles, or triangles are congruent with a third pair of lines, angles, or triangles, then the first pair of lines, angles, or triangles are also congruent with the third pair of lines, angles, or triangles. As was previously mentioned, the transitive property creates an equivalence relationship between 3 lines, 3 angles, and 3 triangles. According to the definition of the transitive property of congruence in geometry, if any two angles, lines, or forms are, respectively, congruent with a third angle, line, or shape, then the first two angles, lines, or shapes are likewise congruent with the third angle, line, or shape.

At the beginning of spring, Allison planted a small sunflower in her backyard. When it was first planted, the sunflower was 15 inches tall. The sunflower then began to grow at a rate of 2 inches per week. How tall would the sunflower be after 9 weeks?
How tall would the sunflower be after w weeks?
Height after 9 weeks?
During plantation sunflower was 15 inches tall , then grow at the rate of 2 inches per week , after 9 weeks sunflower would be 33 inches tall.
As given in the question,
During plantation sunflower was 15 inches tall
Rate of growth per week = 2 inches
Let x be the number of weeks and y be the height of the plant.
Required height :
y = 15 + 2x
Change in the height of sunflower after 9 weeks
y =15 +2x
= 15 + 2(9)
= 15 +18
= 33 inches

p < - 5.8 + 3.6
p < -2.2
So p is strictly smaller than -2.2, then we will have an open circle at the number -2.2 and a line or arrow that extends to the left.

A rental car company charges $40 per day to rent a car and $0.08 for every mile driven. Justin wants to rent a car, knowing that:
He plans to drive 125 miles.
He has at most $170 to spend.
Write and solve an inequality which can be used to determine xx, the number of days Justin can afford to rent while staying within his budget.
The inequality we want to find is:
$40 + $0.08*x ≤ $170
Where x is the number of miles Justin can drive, and the solution is:
x ≤ 1,625
How to write the inequality?We know that there is a fixed cost of $40 plus $0.08 for every mile driven. So if you rent the car and drive for x miles, the total cost is:
C(x) = $40 + $0.08*x
We know that Justin has at most $170 to spend, so we can write the inequality:
$40 + $0.08*x ≤ $170
Solving this for x, we get:
$0.08*x ≤ $170 - $40
$0.08*x ≤ $130
x ≤ $170 /$0.08
x ≤ 1,625

Considering the angle relations when two parallel lines are cut by a transversal, the measures of the angles are given as follows:
18. <4 = 56º.
19. <3 = 132º.
20. <2 = 55º.
21. <8 = 120º.
22. <6 = 129.5º.
23. <2 = 61.3º.
Parallel lines cut by transversalWhen two parallel lines are cut by a transversal, there are multiple relations among the angles, which are going to be used to solve this question.
In item 18, the angles 1 and 4 are consecutive interior angles, hence they are supplementary angles, meaning that the measure of angle 4 is found as follows:
<4 + <1 = 180º
<4 + 124º = 180º
<4 = 56º.
In item 19, angles 2 and 3 are also consecutive interior angles, hence:
<2 + <3 = 180º
48º + <3 = 180º
<3 = 132º.
For item 20, angles 2 and 4 are alternate interior angles, hence they are congruent and their measures are given by:
<2 = <4 = <55º.
For item 21, angles 6 and 8 are alternate exterior angles, also being congruent, hence their measures are given as follows:
<6 = <8 = 120º.
For item 22, angles 7 and 6 are same side exterior angles, meaning that they are supplementary, hence:
<6 + <7 = 180º
<6 + 50.5º = 180º
<6 = 129.5º.
For item 23, the relation is the same as item 19, hence:
<3 + <2 = 180º
<2 = 180 - 118.7
<2 = 61.3º.
