Eighteen technicians in a cell phone repair shop are randomly selected to participate in a study comparing two screen repair techniques. They are randomly assigned one of the two techniques. The manager trains 9 technicians on one technique and trains the other 9 technicians on the second technique. He then records the number of screen repairs each technician does in one week. Which inferential statistical test would be most appropriate for this scenario?
A one-sample z-test
A paired t-test
A chi-square goodness-of-fit test
A one-sample t-test
A two-sample t-test
Answer:
a two sample t test
Step-by-step explanation:
The inferential statistical test that would be most appropriate for this scenario is a two-sample t-test option fifth is correct.
What is a t-test?A t-test is a hypothesis-testing technique for analyzing the means of one or two populations. A t-test can be used to see if a single group differs from a known value, if two groups differ from each other (an independent two-sample t-test), or if paired measurements show a significant difference.
Based on the information provided, there are two techniques, each with nine technicians. The sample sizes are tiny, in other words. Furthermore, the two samples are unrelated to one another. As a result, a two-sample t-test is appropriate.
Thus, the inferential statistical test that would be most appropriate for this scenario is a two-sample t-test option fifth is correct.

After the Sutton family finished their meal at a local restaurant, the waiter brought them a check for $48.86. If Mrs. Sutton leaves a 20% tip, what amount of tip wages will the waiter receive?
What will the total meal cost?
How much should you tip a hairstylist, pizza delivery person, and taxi driver?
Answer:
58.23
Step-by-step explanation:
The amount of tip wages will the waiter receive will be $9.77. Then the total meal cost will be $58.63.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
After the Sutton family finished their meal at a local restaurant, the waiter brought them a check for $48.86. If Mrs. Sutton leaves a 20% tip. Then the amount of the tip will be
Tip = 20% of $48.86
Tip = 0.20 x $48.86
Tip = $9.772
Then the total meal cost will be
Total cost = $48.86 + $9.772
Total cost = $58.63
The amount of tip wages will the waiter receive will be $9.77. Then the total meal cost will be $58.63.

The anticoagulant warfarin is often used as a pesticide against house mice, Mus musculus. Some populations of the house mouse have acquired a mutation in the vkorc1 gene from hybridizing with the Algerian mouse, M. spretus (Song et al. 2011). In the Algerian mice, this gene confers resistance to warfarin. In a hypothetical follow-up study, researchers collected a sample of house mice to determine whether presence of the vkorc1 mutation is associated with warfarin resistance in house mice as well. They fed warfarin to all the mice in a sample and compared survival between the individuals possessing the mutation.
a. Identifiy the two variables measured in the study and indicate which is the explanatory and which is the response variable.
i. Explanatory:
ii. Response:
b.Identify the scales on which each of the two variables is quantified (nominal, ordinal, inteval, ratio).
c. What do you think was the intended target population for the study? Why?
d. Do you consider the follow up study to be a manipulative experiment or an observational experiment? Explain.
e. Do you think the researchers used a random sample? Explain.
Solution :
Response variable is the variable whose value is to be predicted or the value is influenced. It is also known as the dependent variable. While the variable which affects the values and is used for the prediction is known as the explanatory variable or the independent variable.
i. The explanatory variable in the study is the Vkorc I mutation.
ii. The response variable in the study is the Warfarin resistance.
b). The explanatory variable which comes under the nominal scale in this study is the Vkorc I mutation.
While the response variable or the independent variable that comes under the interval scale in the study is the Warfarin resistance.
c). The group of the individuals in this study is called as population. The target population in the study is the house mouse which is required as the mutation in Vkorc 1 gene from the hybridizing with Algerian mouse.
d). The study is a manipulative experiment as the changes that have already introduced in house mice and the treatments are under control.
e). No in this study the researcher did not use any random sample.

This isn't right because you are adding the area of both rectangles together and in the first choice the + 7 should be 7y because y is the height which is why the 4th choice is correct and the second choice if you distribute you get 5y + 7y which is the same so that would be right as well.

If a man were to sell his T.V set for 7200, he would have lost 25%. For what price must he sell it to
Answer:
Step-by-step explanation
S.P of a t.v = rs 7200
Loss % = 25%
Therefore, C.P = S.P (100/100-loss)
=7200(100/100-25)
=7200 x 100/75
=9600
So,now C.P = 9600
Profit% = 25%
Therefore, S.P = C.P (100+profit/100)
=9600(100+25/100)
=9600 x 125/100
=12000
So,the price he should sell to gain 25%
=12000

Camden invested $7,200 in an account paying an interest rate of 4.4% compounded monthly. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $13,140?
The value of the account to reach $13,140 will take 14 years assuming no deposits or withdrawals are made .
What is compound interest?Compound interest is an interest accumulated on the principal and interest together over a given time period. The interest accumulated on a principal over a period of time is also accounted under the principal.
Formula of compound interest :[tex]A = P (1+ \frac{r}{100} )^{n}[/tex]
Where,
A = final Amount
P = initial principal
r = rate per annum
n = time in years
According to the question
Camden invested (P) = $7,200
Interest rate per month (r) = 4.4%
Amount to reach = $13,140
now , using Formula of compound interest
[tex]A = P (1+ \frac{r}{100} )^{n}[/tex] ere , n = n/12 (as concluding monthly wise )
Substituting the values
[tex]13140 = 7200 (1+ \frac{4.4}{100} )^{\frac{n}{12} }[/tex]
1.825 = [tex](1+ \frac{4.4}{100} )^{\frac{n}{12} }[/tex]
1.825 = [tex](1..044 )^{\frac{n}{12} }[/tex]
n ≈ 168 months (approx.)
n = 14 years (nearest year)
Hence, the value of the account to reach $13,140 will take 14 years assuming no deposits or withdrawals are made .

A road is
4/5
of a mile long. A crew needs to repave 2/5
of the road. How long is the section that needs to be repaved?
Write your answer in simplest form.
Answer: 20/10
Step-by-step explanation:
Take (calculate) 4/5 of 2/5 mile:
4x5= 20
---- * ---- = 20/10
2x5= 10
The section that needs to be repaved is 1/2 of a mile.
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now it is given that,
Length of road = 4/5 of a mile
Road needs to repave = 2/5 of the road
Thus, road needs to repave = 2/5 of 4/5
⇒ road needs to repave = (2*4)/(5*5)
⇒ road needs to repave = 10/20
or, road needs to repave = 1/2
Thus, the section that needs to be repaved is 1/2 of a mile.

La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.
Sabemos que uso 2/3 de esa cantidad para hacer un guiso.
Entonces ella usó 2/3 de 3/4 kilogramos de arroz.
Entonces ella usó:
(2/3)*(3/4) kg de arroz.

(2*3)/(3*4) kg de arroz.
(6/12) kg de arroz
(1/2) kg de arroz.
