Answer:

The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.

Step-by-step explanation:

Let p1 be the sample of 1000 adults chosen in 2012 and

p2 be the sample of 1100 adults chosen in 2010

Part a:

The hypothesis that can be used to test for a significant difference between the population proportions for the two years is:

H0: p1-p2= 0           against the claim      Ha: p1-p2≠0

Part b:

The sample proportion indicating that their financial security was more that fair in 2012 is

p1^= 410/1000= 0.41

In 2010 is:

p2^= 385/1100= 0.35

Part c:

p^c= 410+385/1000+1100= 0.3785

q^c= 1-p^c= 1-0.3785= 0.6124

The critical region is z > ±1.96

The test statistic is

z= p1^- p2^ / sqrt ( p^cq^c( 1/n1+ 1/n2)

z= 0.41-0.35 /sqrt( 0.3785*0.6124(1/1000 +1/1100)

z=  0.06 / 0.021036

z= 2.85

Conclusion

The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.

P- value :  0.00466

The result is significant( accept the null hypothesis) for  value less than 0.05

Part d:

                                                     2012                         2010

Sample                                       1000                           1100

Proportions                               0.41                             0.35

Standard Error               √0.41( 0.59)/1000        √0.35( 0.65)/1100

                                               = 0.0155                0.01438

Standard Error for the difference = √0.0155² + 0.01438² =0.0211

p1-p2 ± z* standard error for the difference

0.41-0.35 ± 1.96 *( 0.0211)

0.06 ± 0.041356

-0.018644,   0.101356

The 95 % confidence interval estimate is (-0.018644,   0.10135

Answer:

[tex]dx[/tex] denotes an infinitesimal displacement along [tex]x[/tex]

Step-by-step explanation:

The integration refers to the antiderivative of a function. The inverse process of differentiation is the integration.

The integration is used to find the volume and area under the curve.

In ∫ [tex]2x\,\,dx[/tex]

∫ denotes the sign of integral,

[tex]dx[/tex] denotes an infinitesimal displacement along [tex]x[/tex],

[tex]2x[/tex] is the part to be integrated.

Answer:

The second one

Step-by-step explanation:

Since the equation is X is greater than or equal to 11, because of the line under it, the "or equal to" it is a closed dot. (If it didn't have that line under it, it would be an open dot.) And, how I like to explain which way the blue arrow goes, the ">" kind of looks like the tip of an arrow, so the blue arrow should go the same way. For example, ">" seems like an arrow going this way "-->", or "<" seems like an arrow going this way "<--"!

Answer:

B, is the correct option.

Step-by-step explanation:

because x is greater than or equal to 11.

Answer:

Option B. 4

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 60 °

Opposite (Fe) = 4√3

Adjacent (DE) = x

The value of x can be obtained by using the Tan ratio as illustrated below:

Tan θ = Opposite / Adjacent

Tan 60 = 4√3 / x

√3 = 4√3 / x

Cross multiply

√3 × x = 4√3

Divide both side by √3

x = 4√3 /√3

x = 4

Thus, the length of DE is 4

Answer:

There will be 132 seats in row 25

Step-by-step explanation:

1st term = 12

common difference = 5

f(x) = 12 + 5(x - 1)

f(25) = 12 + 5(25-1)

f(25) = 12 + 5(24)

f(25)= 12+120

f(25)=132

There will be 132 seats in row 25

The number of seats is 137 with the general equation [tex](12+5n)[/tex] seats

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Let the row number is [tex]n[/tex]

The number of seats in the first row is 12

As per the plan, each row shall have 5 more seats.

So, in the first row seats=12

In the second row seats=[tex]12+5[/tex]

In the third row seats=[tex]12+2\times5[/tex]

[tex]n^{th}[/tex]  row seats=[tex]12+5n[/tex]

So, the number of seats in any row is [tex]12+5n[/tex]

Where [tex]n[/tex] is the row number

Now, for 25 rows, [tex]n=25[/tex] then,

The number of seats is,

[tex]12+5\times25=137[/tex]
