Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
(a) Identify the population of interest and the sample in this study.
(b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
Step-by-step explanation:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Sample size is 160 which is above 30.
Thus, we can say;
Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
convert 0.5t5kg5hg to kilogram
Answer:
505.5kg
Step-by-step explanation:
To convert 0.5t5kg5hg to kilogram, first we need to convert 0.5t and 0.5hg to kg as shown;
1t = 1000kg
0.5t = 0.5 *1000
0.5t = 500kg
Similarly
1hg = 0.1kg
5hg = 5 * 0.1
5hg = 0.5kg
Adding up;
0.5t5kg5hg = 500kg+5kg+0.5kg
0.5t5kg5hg = 505.5kg
Hence the conversion to kg is 505.5kg
Given f(x) = 5x4 – x2 + 6x – 1. What is Limit of f (x) as x approaches negative 1?
–3
–13
–25
–29
Answer:
-3
Step-by-step explanation:
The limit of the given function f(x) = 5[tex]x^{4}[/tex] – x2 + 6x – 1 approach negative 1 will be -3 so correct option will be (A).
What is limit?Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.
In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.
Because the value of that function at that point doesn't define.
For example, limits tend to 0 of sine x, limits tend to infinite of cosx.
Given that the function
5[tex]x^{4}[/tex] – x2 + 6x – 1
Limit is from x is tends to -1
[tex]\lim_{x \to \-1} f(x)[/tex] = 5(-1)⁴ - (-1)² +6(-1) -1
⇒ -3 hence it will be the correct answer.

Given tan theta = -2 and pi/2 < theta < pi; find cos2theta.
a. - 4/3
b.- 4/5
c. 3/4
d. - 3/5
PLEASE HELP ASAP
Answer:
Cos 2theta = -3/5
Step-by-step explanation:
Given that;
tan theta = -2
tan theta = -2/1 = opp/adj
hyp^2 = (-2)^2+1^2
hyp = √4+1
hyp = √5
sin theta = opp/hyp
sin theta = -2/√5
Cos theta = adj/hyp
Cos theta = -2/√5
Cos 2theta = 1-2sin^2 theta
Cos 2theta = 1- 2(-2/√5)^2
Cos 2theta = 1- 2(4/5)
Cos 2theta = 1- 8/5
Cos 2theta = (5-8)/5

Write your answer as a comma-separated list giving the probabilities in the same order as in (a)
Answer:
a) 0 , 1
b) 0.56 , 0.06
Step-by-step explanation:
X = 0.2

Find the distribution of X + Y
a) All the possible values of X + Y
The possible values of X + Y are ; 0,1
b) The probabilities that X + Y takes each of the values
P(X+Y=0 ) = ( 1-0.2 )*(1-0.3) = 0.56

Find lateral surface
area of the play tent.
h = 4 in
14 in
5 in
5 in
W
6 in
Answer:
224 in.²
Step-by-step explanation:
The tent has a shape of a triangular prism. So, we are looking for the Lateral surface area of a triangular prism.
Lateral surface area of a triangular prism = Perimeter of base × height of prism
Perimeter of base = 5 + 6 + 5 = 16 in.
Height of prism = 14 in.
Plug in the values
Lateral Surface Area = 16 × 14 = 224 in.²

-gallon jug of milk every 3 days. At what rate do they drink milk?
Simplify your answer and write it as a proper fraction, mixed number, or whole number
Answer:
4 gallons/1 day
Step-by-step explanation:
What is a rate? A rate is writing a ratio in fraction form. A ratio is the proportion of two things. (ex: for every 1 dog, there are two cats.)
Creating the ratio: For the ratio, there is no given amount of which one needs to come first, but because it is about the milk, I put that first. In the problem it says 12 gallons for 3 days so: 12/3
Simplifying: To simplify, think of the largest factor between the two numbers. If you can't immediately, think of one factor in common and keep simplifying. In this case, 4 is the greatest common factor between these. To simplify, divide both sides by four, and that is your answer: 4: 1

[tex]r = \sqrt\frac{2A}{\theta}[/tex]
A = 3pi

There are only seven days left until we launch of our new product and we only have $668 left in our promotion budget we need to spend $85 on the last day can you please calculate how many dollars a day we can spin on the remaining days
Answer:
$97.17
Step-by-step explanation:
First, subtract 85 from 668:
668 - 85
= 583
This means that our budget for all of the days excluding the last day is $583
To find how much can be spent on the remaining days, divide 583 by 6:
583/6
= 97.17
So, approximately $97.17 can be spent on the remaining days

Answer:
a) radius: 6 (m); mass: 22 (kg)
b) volume: 19 (m³)
c) d ≈ 2.8×10^3 kg/m³
Step-by-step explanation:
The order of magnitude is the exponent of 10 when the number is written in scientific notation.
a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.
mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.
__
b) The volume is ...
V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.
__
c) The ratio of mass to volume is ...
d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.
