In previous years, less than 3300 dollars, on average, is spent on pay per click annually. The digital marketing freelancer suspects this average has increased in recent years. If the digital marketing freelancer chooses to use the rejection region approach for their hypothesis test, what do they need to calculate in order to compare with the critical value

Answers

Answer 1

Answer:

Test statistics

Step-by-step explanation:

A test statistic is calculated to compare with the critical value approach. The critical value is found by choosing any value of significance level ∝ = 0.05, 0.1 or 0.01  . Mostly 5% is preffered .

The the calculated value of the test statistic is compared with the chosen value rejection region that whether it falls in the critical region or not.

The test statistic is applied on the conditions given. For example comapring many results can be done by using chi square or  comparing two means can be done by t test or testing the variation can be done by F - test.

In the given problem a z test would be used.

Answer:

50.24

Step-by-step explanation:

The formula for area is pi · r²

But, because usually people want it simplified instead of a ton of decimal numbers following, pi is rounded to 3.14. And the radius in this case is 4. And the ² means squared, so we have to do 4 · 4 to square it.

So, now our formula is 3.14 · 4 · 4 which equals 50.24

Step-by-step explanation:

First we open the parentheses:

2*3x-2*7+18=10

Now we multiply:

6x-14+18=10

6x+4=10

Now we move +4 to the other side so it will be -4

6x=10-4

6x=6

We divide both sides by 6

A circle is formed when a cone intersects a plane as shown in the drawing.

What is a circle?

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

A cross section is defined as the process where a surface is shown when a straight cut is made by something. We are given when a cone is intersected by a plane horizontally the shape of the cross - section is a circle .

When the cone is intersected vertically by a plane the shape of the cross- section will be a triangle. Hence the shape of the cross section depends according to the cut.

Cross section is usually used to find what is there inside the object.

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual. a. X ~ __N___(_66____,__2.5___) b. Find the probability that the person is between 65 and 69 inches. Include a sketch of the graph, and write a probability statement.

Answers

Answer:

0.54035

Step-by-step explanation:

Given that :

Mean, m = 66 inches

Standard deviation, s = 2.5 inches

P(65 < X < 69)

P(X < 69) - P(X < 65)

((69 - 66) / 2.5) - ((65 - 66) / 2.5)

P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))

P(Z < 1.2) - P(Z < - 0.4)

0.88493 - 0.34458

= 0.54035

f(0).

This is the value of f when [tex]x = 0[/tex]. So

?
The mean of the 4 numbers on Ed's cards is 10
Work out the number on the 4th card.

Answers

Answer:

7

Step-by-step explanation:

Let's call the missing card number "x".

The mean is the sum divided by the number of elements, so we know that:

[tex]\frac{12 + 6 + 15 + x}{4} = 10\\~\\12 + 6 + 15 + x = 40\\33 + x = 40\\x = 7[/tex]

The number on the 4th card is 7 according to the given question when The mean of the 4 numbers on Ed's cards is 10

To work out the number on the 4th card, we can use the information given about the mean of the four numbers.

Mean is calculated by summing all the values and then dividing by the number of values. In this case, the mean is 10 and there are four numbers.

Given:

Mean = 10

Number of cards = 4

To find the sum of the four numbers, we multiply the mean by the number of cards:

Sum of the four numbers = Mean * Number of cards

Sum of the four numbers = 10 * 4

Sum of the four numbers = 40

Now, let's find the number on the 4th card. We subtract the sum of the three known numbers from the sum of the four numbers:

Number on the 4th card = Sum of the four numbers - Sum of the three known numbers

Number on the 4th card = 40 - (12 + 6 + 15)

Number on the 4th card = 40 - 33

Number on the 4th card = 7

Therefore, the number on the 4th card is 7.
