In explaining why their country is an attractive place to invest, the Minister of Commerce from Turgistan has argued that the political problems have been exaggerated and that fewer people have been imprisoned for political reasons than you have been led to believe. However, Amnesty International reports that one third of the prisoners in Turgistan are political prisoners. A representative from your company visited a prison and sampled 500 prisoners in Turgistan, concluding that 90 of them are political prisoners. Test the hypothesis, at the 5% significance level, that one third of the prisoners in Turgistan are political prisoners.
Required:
a. Does this data support the Minister of Commerce or Amnesty International?
b. What other issues might be important when evaluating this data?
Answer:
a
This data does not support the Minister of Commerce or Amnesty
International
b
Another issue that is important when evaluating this data is the judicial system of the Turgistan
Step-by-step explanation:
From the question we are told that
The sample size is n = 500
The number of political prisoners is k = 90
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : p = \frac{1}{3} = 0.33[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.33[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{90}{500}[/tex]
=> [tex]\^ p = 0.18[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\^ p - p}{\sqrt{\frac{p (1- p)}{n} } }[/tex]
=> [tex]z = \frac{0.18 - 0.40}{\sqrt{\frac{0.33 (1- 0.33)}{500} } }[/tex]
=> [tex]z = -7.1429 [/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P( Z > -7.1429)[/tex]
From the normally distribution table
The probability of [tex]P( Z > -7.1429) = 0[/tex]
=> [tex]p-value = 2 * 0[/tex]
=> [tex]p-value = 0[/tex]
From the value obtained we see that the [tex]p-value < \alpha[/tex] hence the decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that this data does support the Minister of Commerce or Amnesty International

600 students are studying in a private
school, the average monthly fee of a
student is Rs. 1200. How much amount for
tax does the school pay to the government
as education service tax at the rate of 1% in
a year? *
Answer:
600 ×1200=720,000
720,000×12=8,640,000
8,640,000×1%=8,640,000÷100%=86,400

q(x)= -2x+1
r (x)=x²+2
Find the value of r r(q (2)).
Answer:
r(q(2)) = 11
Step-by-step explanation:
given r(x) = x^2 + 2, and q(x) = -2x + 1.
Here is the equation to the composite function:
r(q(x)) = (-2x+1)^2 + 2 = 4x^2-4x+3 .
Then just substitute the input and solve:
r(q(2)) = 4(2)^2- 4(2) + 3 = 16 - 8 + 3 = 16 - 5 = 11
______________________________
Or if you don't like this, first find the answer to q(2) = -2(2) + 1 = -3
Then substitute this value into the second equation r(x).
r(x) → r(-3) = (-3)^2 + 2 = 9 + 2 = 11
A delivery driver earns a fixed amount for each delivery she makes, and
yesterday her average hourly wage was $16.50 an hour. If she worked 6 hours
yesterday and made 11 deliveries, how much does she earn for each delivery
made?
O A. $9.90
O B. $9.00
O C. $5.50
O D. $5.00
Answer:
9 dollars or B
Step-by-step explanation:
16.50 (hourly wage) x 6 (hours worked) = 99 dollars
$99/11 deliveries= 9 dollars per delivery.

5. Paul is x years old.
Rebecca is four times older than Paul.
Gemma is 10 years older than Paul.
the sum of their ages is 82 Years.
(a) Form a simplified equation in terms of x
(b) Solve the equation and work out each persons age.
Answer: A) The equation will be x + 4x + x + 10 = 82 B) Paul's age is 12, Rebecca's age is 48 and Gemma's age is 22.
Step-by-step explanation:
We will represent Paul's age by the equation p= x where p is Paul
We will represent Rebecca's age by the equation r = 4x Where r is Rebecca
We will represent Gemma's age by the equation g = x + 10 where g is also Gemma's age.
We given that the sum of their ages is 82 years so meaning that x + 4x + x + 10 has to equal 82.
A) The equation will be x + 4x + x + 10 = 82
Solve for the x equation to find Paul age because his age is x.
B) (x) + (4x) + (x+10) = 82 combine like terms on the left side
6x + 10 = 82
-10 -10
6x = 72
x= 12
Paul age is 12.
r= 4(12)
r = 48
Rebecca's age is 48.
g= 12 +10
g= 22
Gemma's age is 22.
RQT is a straight angle. What are mRQS and mTQS?
Somone help please
Answer:
RQS=100 & TQS=80
Step-by-step explanation:
add them and set it equal to 180 because it is a straight line
9x+1 + 7x+3 = 180
16x+4=180 (subtract 4 from both sides)
16x=176 (divide 16 from both sides)
x=11 (plug 11 into the angles)
9(11)+1=RQS & 7(11)+3=TQS
only have to solve one of them and subtract it from 180 to get the second angle since they are supplementary
Answer:
RQS=100 & TQS=80
Step-by-step explanation:
add them and set it equal to 180 because it is a straight line
9x+1 + 7x+3 = 180
16x+4=180
16x=176
x=11
9(11)+1=RQS & 7(11)+3=TQS
you only have to solve one of them and subtract it from 180 to get the second angle since they are supplementary .
hope this helped!

A large hamburger (e.g., Whopper®) sandwich contains 628 kcal and 36 grams of fat. Approximately what percentage of the total energy is contributed by fat?
Answer:
Step-by-step explanation:
Total energy of the sandwich = 628kcal
Mass of fat contained = 36grams
Convert gram to kcal
1gram = 9kcal
36 grams = x
x = 36×9
x = 324kcal
Hence the fat contains 324kcal
%fat contained = fat(in kcal)/total calorie × 100%
%fat contained = 324/628 × 100%
%fat contained = 1/2 × 100%
%fat contained = 50%
Hence approximately 50% of the total energy is contributed by fat.

Hopefully that helped a little
Step-by-step explanation:
The expression (x + 5) is a factor of given function f(x) So the remainder of the function will be zero.
Remainder theorem:
The given function,
[tex]f(x) = x^3+3x^2-25x-75[/tex]
Equate (x + 5) is equal to 0.
x + 5 = 0
x = -5
Substitute x = -5 in given equation.
[tex]f(x) = x^3+3x^2-25x-75\\\\f(-5) = -5^3+3(-5)^2-25(-5)-75\\\\f(-5) = 0[/tex]
Since f(-5) = 0. thus, (x + 5) is a factor of given function f(x).

If paper clips are 7/8 of an inch long and cost $0.02 to make, how much would it cost to produce enough paper clips to make a line, end to end, that stretches 56 inches?
Answer:
$1.12
Step-by-step explanation:
When you multiply 8/7 of 56, you get 64.
This shows that you will need 64 paperclips to make 56 inches worth of paper clips. If each paper clip costs two cents, you need to multiply 56 paperclips by 2 cents. 56x0.02=1.12 so it will cost you 1 dollar and twelve cents
