Consider the following two questions designed to assess quantitative literacy.
What is 15% of 1000?
A store is offering a 15% off sale on all TVs. The most popular television is normally priced at $1000. How much money would a customer save on the television during this sale?
Suppose the first question is asked of 200 randomly selected college students, with 168 answering correctly; the second one is asked of a different random sample of 200 college students, resulting in 147 correct responses. Carry out a test of hypotheses at significance level 0.05 to decide if the true proportion of correct responses to the question without context exceeds that for the one with context. (Use p1 for the true proportion students who answered the question without context correctly and p2 for the true proportion of students who answered the question with context correctly.)
State the relevant hypotheses.
H0: p1 − p2 = 0
Ha: p1 − p2 < 0H0: p1 − p2 = 0
Ha: p1 − p2 ≠ 0 H0: p1 − p2 = 0
Ha: p1 − p2 > 0H0: p1 − p2 < 0
Ha: p1 − p2 = 0H0: p1 − p2 > 0
Ha: p1 − p2 = 0
Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)
z=P-value=
State the conclusion in the problem context.
Fail to reject H0. The data does not suggest that the true proportion of correct answers to the context-free question is higher than the proportion of right answers to the contextual one.Reject H0.

The data suggests that the true proportion of correct answers to the context-free question is higher than the proportion of right answers to the contextual one.
You may need to use the appropriate table in the Appendix of Tables to answer this question.
Answer:
A customer would save $ 150 on the television during this sale and pay
$ 850.
Reject H0. The data suggests that the true proportion of correct answers to the context-free question is higher than the proportion of right answers to the contextual one
Step-by-step explanation:
15% of 1000
=0.15 *1000= $ 150
A customer would save $ 150 on the television during this sale.
p1 = the true proportion students who answered the question without context = 168/200
p2 = the true proportion of students who answered the question with context correctly = 147/200
The null and alternate hypotheses are
H0: p1 − p2 = 0 i.e the true proportion of correct responses to the question without context is the same as that for the one with context
against the claim
Ha: p1 − p2 > 0 that is the true proportion of correct responses to the question without context exceeds that for the one with context
2) The significance level is set at 0.05
3) The critical region is z > ± 1.645
4) The test statistic
Z= p1-p2/ sqrt [pcqc ( 1/n1+ 1/n2)]
Here p1= 168/200= 0.84
and p2= 147/200=0.735
pc = 168+147/200+200
pc= 315/400= 0.7875
qc= 1-pc= 1-0.7875=0.2125
5) Calculations
Z= p1-p2/ sqrt [pcqc ( 1/n1+ 1/n2)]
z= 0.84-0.735/√ 0.7875*0.2125( 1/200+ 1/200)
z= 0.105/0.0409076
z= 2.5667
6) Conclusion
Since the calculated value of z= 2.5667 lies in the critical region the null hypothesis is rejected and it is concluded that the true proportion of correct responses to the question without context exceeds that for the one with context.
The value of z is 2.5668.
The value of p is 0.01016

find the equation of the linear function represented by the table in slope intercept form
The equation of the linear function represented by the table in slope intercept form is y = -4x - 5.
What is slope-intercept form?
The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
Given two points (x,y), the slope is the change in y divided by the change in x.
The points are (1,-9) and (3,-17) -
m = (y2-y1)/(x2-x1)
m = [-17-(-9)]/(3-1)
m = -8/2
m = -4
Then the slope equation will be -
y = -4x + b
Taking points (1,-9) and substituting in the equation to get the value of b -
-9 = -4(1) + b
-9 = -4 + b
-9 + 4 = b
b = -5
Therefore, the slope intercept form of equation is y = -4x - 5.

A tank is 80c ,nu 60cm by 75cm, find the volume of water that will fill up
A tank that is 80 cm tall and has a base that is 60 cm by 75 cm.
To find the volume of the tank, you can use the formula for the volume of a rectangular prism, which is:
Volume = length * width * height
Using the dimensions given, we can plug them into the formula as follows:
Volume = 60 cm * 75 cm * 80 cm = 4,500 cm^3
This means that the tank has a volume of 4,500 cubic centimeters, and it would take 4,500 cubic centimeters of water to fill it up
Learn more about volume:
https://brainly.com/question/463363
Answer:
Step-by-step explanation:
To find the volume of water that will fill up a tank that is 80 cm tall, 60 cm wide, and 75 cm deep, you can use the formula for the volume of a rectangular prism. The formula for the volume of a rectangular prism is length x width x height, so in this case, the formula would be:
60 cm x 75 cm x 80 cm = 36,000 cm^3
So the volume of water that will fill up the tank is 36,000 cubic centimeters.
Alternatively this also can be written as 806075 cubic cms

Solve the exponential equation. 1/16 = 64^4 x − 3
Answer:
x=7/12Step-by-step explanation:
1/16=64^4x-3
1/4^2=(4^3)^4x-3
4^-2=(4^3)^4x-3
4^-2=4^3*(4x-3)
Since the bases are equal (to 4), the exponents must be equal to each other.
-2=3*(4x-3)
-2=12x-9
-2+9=12x
7=12x
7/12=x
x=7/12
So the answer is x=7/12

What are Word Problems ?A word problem is a type of mathematics exercise where the majority of the issue's context is supplied in spoken language as opposed to mathematical notation.
A math word problem is a question that is phrased as one or more sentences and asks students to use their mathematical understanding to solve an issue from "real world." In order for kids to understand the word problem, they must be familiar with the terminology that goes along with the mathematical symbols that they are used to.
Word issues, also known as narrative problems, may be found in both daily life and the Common Core State Standards for every school level, from K to 12. For everything from counting pennies to calculating a gratuity, you can utilize the three primary forms of word problems: part-part whole, separate and join, and multiply and divide.
Total money the band has after selling the merch is = $375 + 200 = $575.
Rate for studio is $75 per day.
Total money left = $575 - 75 = $ 500
So number of Hours the band can record there music is= 500/50 = 10hrs.

The graph of g(x) = f(x+4) is the graph of f(x) moved 4 units________
Answer:
to the left
Step-by-step explanation:
This looks backwards to some, but it's correct: replacing x with x + 4 in a function moves the graph 4 units to the left.
The reason?
Just suppose that f(6) = 7. To get f(x + 4) to equal 7, you have to use 2 as a value for x, 4 units less than the 6 that was used before.
See attached image for an example.
