Answer:

Hello your question is poorly written the complete question is attached below

answer :

a) H0 : p1 = p2

  Ha : p1 ≠ p2

b)  Z = -0.58

c) P-value =  0.561915

d) we will reject the Alternative hypothesis

Step-by-step explanation:

For sample 1 ;  n1 = 254 , x1 = 28

For sample 2 ; n2 = 301 , x2 = 38

level of significance ∝ = 0.01

P1 = X1 / n1 = 28 / 254  = 0.1102

P2 = X2 / n2 = 38 / 301 = 0.126

a) Determine the null and alternate hypothesis

H0 : p1 = p2

Ha : p1 ≠ p2

b) Determine Test statistic

we perform a Z-statistic to test the hypothesis

Z = [tex]\frac{p1-p1 }{\sqrt{( p(1-p)*(\frac{1}{n1}+\frac{1}{n2}) ) } }[/tex]  -------- ( 1 )

p =  ( x1 + x2 ) / ( n1 + n2 )

= ( 28 + 38 ) / ( 254 + 301 ) = 0.1189

Where: p = 0.1189 , p1 = 0.1102 , p2 = 0.126 ( input values into equation 1 )

∴ Z = -0.58

c) Determine P-value

P-value =  0.561915 ( using excel function )

d) conclusion : since p-value > 0.01 ( level of significance ) we do not reject the null hypothesis.  therefore it proves that p1 = p2

Answer: ty for the points

Step-by-step explanation:

x+-3(y+3)2+5

Answer:

No this is not true.

Step-by-step explanation:

An integer is a whole number and not a fraction.

An integer can be 0, 1, 3, 16, 18, 100, etc.

But an integer is either 0 - infinity.

For 8 * 10^m to equal 8, it has to be a fraction.

So, m can not be a integer. This is wrong.

Hope this helps! :)

The answer is B, 721

Step-by-step explanation:

edge 2021

The total computers will be sold in July will be equal to 98 computers.

The percentage represents a value divided by 100. In this way, saying 25% of a value is the same as saying 25 out of 100, that is, 25 divided by 100. And to find the exact number of absentees in the event, just multiply the whole by the percentage

So in this case, we have the information that:

Using the percentage we have:

[tex]p=\frac{148}{223} = 0.6637[/tex]

This value in percentage that will be:

[tex]0.6637*100\%= 66.37\%[/tex]

Because of the same percent rate, the amoutns sold in June:

[tex]66.37\%*148=98[/tex]

Answer:

The limit of a sum is equal to the sum of the limits.

Step-by-step explanation:

The limits of a constant times a function is equal to the constant times the limit of the function.

Answer:

x = 9

y = 3

Step-by-step explanation:

2x + 2y = 24 is the same as x + y = 12

using substitution, x = 12-y

12 - y = 3y

12 = 4y

y = 3

x = 3(3)

x = 9

The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given system of equations,

2x+2y= 24

x=3y

Take common 2 from 2x+2y= 24 as

2(x + y) = 24

Divide by 2 into both sides

x + y = 12

Hence "The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12".

Answer:

The step that a mistake first occurs is in step 1.

Step-by-step explanation:

In step one, the constants in the parenthesis went from 24 + 3 + 10 to 8 + 10, which is essentially impossible, so step 1 was the step where a mistake first occurred.

Answer:

X=11

Z=73

Step-by-step explanation:

So vertical angles are equal so to find X

107=12x-25

Solve the equation

x=11

4 angles are 360 degrees, we know 2 angles.

107+107= 214

360-214= 146

146 is the two angles added up, divide them by 2 to find each side

146/2= 73

Z=73

Answer:

hello your question has some missing information attached below is the missing information

answer : mean ratio of estimate = 117.62

              standard error ( SE ) = 3.9765

Step-by-step explanation:

Given data : n = 20,  μx = 10.3  , N = 1132

∑ age ( yi) = ( 125 + 119 + --------- + 99 ) =  2148

∑ ( Y - rX)^2 = 6116.728

mean of age ( y ) = ∑ y / 20 =  2148 / 20 = 107.4

mean of diameter ( x ) = ∑x /20 = 188.1 / 20 = 9.405

∴ ratio estimate  = y /x = 107.4 / 9.41 = 11.4195

i) The mean of ratio estimate

= 11.4195 * μx  = 11.4195 * 10.3 = 117.6204

ii) determine the standard error ( SE )

calculate ; [tex]s^{2} _{r}[/tex] = 1 / ( n-1 ) *  ∑ (Y - rX)^2  = 1/19 ( 6116.728 ) = 321.933

Var (  μr ) = [ ( N - n ) / N*n ]*[tex]s^{2} _{r}[/tex]  =  [ ( 1132 - 20 ) / (1132*20) ] * 321.933

               = 15.81226

therefore the SE = √15.81226 ≈ 3.9765

Answer:

  a) 179

  b) 21

Step-by-step explanation:

When making a Venn diagram for a problem like this, it often works well to fill in the "both" quantity first. Then that is subtracted from the number for grocery to find "grocery only", and from the number for drug store to find "drug store only." The sum of the numbers inside the circles (88+33+58) is the number who shopped at the grocery or drug store. The number who shopped at neither is the difference between this number and the total number of shoppers (200-179).

Shift by 4 to the left on x-axis.

Shift by 6 up the y-axis.

Hope this helps.

Step-by-step explanation:

Hi

3x-y = 4

so y = 4-3x = -3x +4  

now you just have to remplace  X by the first number  given.

for  0  you have :   y = -3*0 +4 = 4

so it's  0; 4  

I let you do the others. No difficulties.
