A hypothesis will be used to test that a population mean equals 10 against the alternative that the population mean is more than 10 with known Ï. What is the critical value of z-score for the following significance levels?A) 0.01
B) 0.05
C) 0.10

Answers

Answer:

A) 2.58

B) 1.96

C) 1.65

Step-by-step explanation:

A hypothesis used to test that

H_o : \mu  = 10

against the alternatives H1 : \mu not equal to 10

if null hypothesis is true, then distribution of test statics follow

Zo = (\bar x - \mu)/((\sigma)/(√(n)))

for two sided alternatives  hypothesis ( H1: \mu \neq 7), then P value is

P = 2[1- \phi(\left | Zc \right |)]                          (1)

a)significance level  \alpha = 0.01

from 1 eq we get

\pi (\left | Zc \right |) = P(Zo<\left | Zc \right |) = 1 - (0.01)/(2)  = 0.995

Therefore  \left | Zc \right | = 2.58    FROM Z TABLE

B) significance level  \alpha = 0.05

from 1st equation we get

\pi (\left | Zc \right |) = P(Zo < \left | Zc \right |) = 1 - (0.05)/(2)  = 0.975

Therefore  \left | Zc \right | = 1.96    FROM Z TABLE

C) significance level  \alpha = 0.10

from 1 eq we get

\pi (\left | Zc \right |) = P(Zo<\left | Zc \right |) = 1 - (0.10)/(2)  = 0.95

Therefore  \left | Zc \right | = 1.65    FROM Z TABLE

Set each pair of parentheses to zero. Solve them as separate equations.

Provide an Example of how to draw transformed figures that are translated, reflected, and rotated.

Answers

Step-by-step explanation:

Translations: When a figure is slid to another place on the coordinate grid (for example if i asked you to move the figure 2 units down and 4 units to the left)

Reflected: When a figure is reflected across the y-axis or the x-axis and both figures are congruent to each other.

Rotated: When a figure is rotated (for example if i asked you to rotate the figure 90 degrees)

The number of roses (r) in a garden increases when the number of weeds (w) decreases. Write the correct equation for this scenario, and solve for the number of roses when there are 5 weeds.Weeds Roses
10 20
20 10

Answers

Number of roses (r) in a garden increases when the number of weeds (w) decreases, this supports an inverse relationship between the two variables. 
The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k

r=200/5
r=40 roses
40 roses when there are 5 weeds.

Answer:

The Inverse variation says that:

y \propto (1)/(x),

then the equation is of the form:

y = (k)/(x) or xy = k

Here, r represents the number of roses and w represents the number of weeds.

As per the statement:

The number of roses (r) in a garden increases when the number of weeds (w) decreases.

by definition of inverse variation:

rw = k          ....[1]

From the given table:

take any points

r = 20 and w = 10 then;

Substitute in [1] we have;

(20)(10)= k  

Simplify:

k = 200

The equation becomes: rw = 200  

We have to find the number of roses when there are 5 weeds.

⇒w = 5

then;

r(5) = 200  

Divide both sides by 5 we get;

r = 40

Therefore, the number of roses are 40 when there are 5 weeds.

Select all the equations that are equivalent to this equation.1/4 (8x + 56) = 20

1; 56 + 8x = 80
2; 14 = 20 – 8x
3; 2x + 14 = 5
4: 2x = 6
5: x = 3

Answers

The equations equivalent to 1/4 (8x + 56) = 20 are

1. 56 + 8x = 80

2.14 = 20 - 8x

4.2x = 6

5. x = 3

What is an equation?

An equation is a mathematical expression that shows the relationship between two variables.

Since we have the equation 1/4(8x + 56) = 20, and we want to find all the equations that are equivalent to it, we solve the equation.

So, we proceed as follows.

1/4(8x + 56) = 20

Expanding the brackets, we have

8x/4 + 56/4 = 20

2x + 14 = 20

Subtracting 14 from both sides, we have that

2x = 20 - 14

2x = 6

x = 6/2

x = 3

Also, in 1/4(8x + 56) = 20

Multiplying through by 4, we have that

8x + 56 = 80

2x + 14 = 20

Subtracting 2x from both sides, we have that

14 = 20 - 2x

So, the equations are

1. 56 + 8x = 80

2.14 = 20 - 8x

4.2x = 6

5. x = 3
