A chi-square test of independence was conducted to investigate whether there is an association between the location where a person lives in a city (north, south, east, or west) and who the person planned to vote for in the upcoming mayoral election (the incumbent or the challenger). A random sample of 100 potential voters was selected, and the hypothesis test had a chi-square test statistic of χ2=9.84 with a p-value of 0.02. Which of the following statements is the correct interpretation of the p-value in context?

(A) There is a 2 percent chance that where a person lives and who that person plans to vote for are independent.

(B) There is a 2 percent chance that where a person lives and who that person plans to vote for are dependent.

(C) There is a 2 percent chance of making a Type II error.

(D) Assuming that the location of where a person lives and who that person plans to vote for are dependent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.

(E) Assuming that the location of where a person lives and who that person plans to vote for are independent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.

-3(x + 4) = 2x - 5

-3x + 4 = 2x - 5

4 = 5x - 5

9 = 5x

1.8 = x

Answers

Answer:

x = -1.4

Step-by-step explanation:

-3(x + 4) = 2x - 5

-3x + (-3*4) = 2x - 5

The mistake was in the above equation where -3 should be multiplied with 4.

-3x -12 = 2x -5

5 -12 = 2x+3x

-7 = 5x

There are 900 students at a school. You receive two thirds of he votes for best student ever! About how many
votes would you expect to receive?

Answers

Answer:

~600 votes

Step-by-step explanation:

Notice how 900 is a multiple of 3. Multiplying by 2/3 is the same as saying as divide the total by 3, then multiply that result by 2. Thusly, 900/3=300 and 300*2=600. Therefore, you should expect around 600 votes.

3. What value of makes a true equivalent fraction statement.
5 30
54
C

Answers

Answer:

[tex]x[/tex] = 9

Step-by-step explanation:

We need to find [tex]x[/tex] which will make an equivalent fraction statement.

[tex]\frac{5}{x} = \frac{30}{54}[/tex]

5 x 6 = 30

[tex]x[/tex] x 6 = 54 (to find [tex]x[/tex] we should do 54 ÷ 6 which = 9)

So:

[tex]\frac{5}{6} = \frac{30}{54}[/tex]

[tex]x[/tex] = 9

hope this helps :)

Answer is 9
5x6 is 30
9x 6 is 54

Here are summary statistics for randomly selected weights of newborn​ girls: n​=250, x_=32.9 ​hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a ​95% confidence level. Are these results very different from the confidence interval 31.9 hg < μ < 34.5 hg with only 19 sample​ values, x_=33.2 ​hg, and s=2.6hg? What is the confidence interval for the population mean ​μ?

Answers

Answer:

a)  ( 31.92 < μ < 33.88 )  

The confidence interval is not very different from the confidence interval given in the question

b) ( 31.74 ,  34.66 )

Step-by-step explanation:

n = 250

x ( mean ) = 32.9

std = 6.9

95% confidence interval

df = n - 1 = 250 - 1 = 249

a) construct confidence interval estimate

calculate for the margin of error

= [tex]t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )[/tex] ( using excel function:  T.INV.2T(0.025,249) )

= 2.255 ( 6.9 / 15.81 )

= 0.98

Hence the confidence interval for the population

= ( x - 0.98 < μ < x + 0.98 )

= ( 31.92 < μ < 33.88 )  

The confidence interval is not very different from the confidence interval given in the question

b) when n = 19

x = 33.2 and std = 2.6

margin of error = [tex]t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )[/tex] = 2.45 * ( 2.6 / 4.36 )  = 1.46

confidence interval

= ( 33.2 - 1.46 , 33.2 + 1.46 )

= ( 31.74 ,  34.66 )

In a sewage treatment plant, a large concrete tank initially contains 440,000 liters of liquid and 10,000 kg of fine suspended solids. To flush this material out of the tank, water is pumped into the vessel at a rate of 40,000 l/h. Liquid containing solids leaves at the same rate. Estimate the concentration of suspended solids in the tank at the end of 4 h. You can assume that the initial concentration of solids in the tank

Answers

Answer:

[tex]Concentration = 8.26kg/m^3[/tex]

Step-by-step explanation:

Given

  [tex]V = 440000L[/tex] --- volume of tank

[tex]m = 10,000 kg[/tex] --- solid mass

[tex]r = 40000L/hr[/tex] --- outflow rate  

Required

Determine the concentration at the end of 4 hours

First, calculate the amount of liquid that has been replaced at the end of the 4 hours.

[tex]Amount = r * Time[/tex]

[tex]Amount = 40000L/hr * 4hr[/tex]

[tex]Amount = 40000L * 4[/tex]

[tex]Amount = 160000L[/tex]

This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced

Calculate the ratio of the liquid replaced.

[tex]Ratio = \frac{Amount}{Volume}[/tex]

[tex]Ratio = \frac{160000L}{440000L}[/tex]

[tex]Ratio = \frac{16}{44}[/tex]

[tex]Ratio = \frac{4}{11}[/tex]

Next, calculate the amount of solid left.

[tex]Amount (Solid)= Ratio * m[/tex]

[tex]Amount (Solid)= \frac{4}{11} * 10000kg[/tex]

[tex]Amount (Solid)= \frac{40000}{11}kg[/tex]

[tex]Amount (Solid)= 3636kg[/tex]

Lastly, the concentration is calculated as:

[tex]Concentration = \frac{Amount (Solid)}{Volume}[/tex]

[tex]Concentration = \frac{3636kg}{440000L}[/tex]

Convert L to cubic meters

[tex]Concentration = \frac{3636kg}{440000* 0.001m^3}[/tex]

[tex]Concentration = \frac{3636kg}{440m^3}[/tex]

[tex]Concentration = 8.26kg/m^3[/tex]

The distance around a triangle is 34 centimeters. If two sides are equal and the length of the third side is 6 centimeters, what is the length of each of the other two sides?

Answers

Subtract 6 from the total then divide by 2.

34-6 = 28

28/2 = 14

The length of the other two sides are 14 cm each

34-6 = 28

28 divided by 2 = 14

So, the length of the two other sides is 14 centimeters.

1Alfred departs from NAMPO Park

an average speed of 88 km/h. He
calls his wife to inform her that he
will arrive in Sasolburg at 8 pm.
Verify, with calculations, whether his
estimate is correct.

You may use the formula:
Distance= Speed x time ​

Answers

Answer:

Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.

Step-by-step explanation:

Since Alfred departs from NAMPO Park at 18:45 and travels to Sasolburg at an average speed of 88 km / h, and he calls his wife to inform her that he will arrive in Sasolburg at 8 pm, to determine if his estimate is correct the following calculations must be performed:

The shortest route from Nampo Park to Sasolburg in South Africa is 139 km via Route 59.

8 PM = 20:00

20:00 - 18:45 = 1:15

139/88 = 1.57

60 x 0.57 = 34.74

Thus, Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.
