What Is The Best Estimate Of The Correlation Coefficient For The Data Set?

Answers

Answer 1

Answer:

it's 0.5

Step-by-step explanation:

Answer 2

The best estimate of the correlation coefficient for the data set is 0.5.

So, option c is the correct answer.

What is the correlation coefficient and how to interpret it?

The correlation coefficient is a measure of how similar two datasets are acting.

The range of correlation coefficient is [-1, 1]

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated. One data increases, and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

If the correlation coefficient comes out as 0, that means both the data sets are uncorrelated with respect to how we compare them.

When the correlation coefficient comes out > 0, that means both datasets' values are positively correlated.

If the correlation coefficient comes out as 1, then the values grow exactly similarly, in the same direction.

The best estimate of the correlation coefficient for the data set is 0.5.

On Marlene's trip to Starved Rock, her average rate of speed for the entire five-hour trip was 62 miles per hour. For the first two hours of her trip, she kept her average speed at 50 miles per hour. Then she realized she was going to be late to meet her friend for dinner, so she started driving faster. What was her average speed for the last three hours of the trip?

Answers

Answer:

70 miles per hour

Step-by-step explanation:

Distance = speed * time

speed = distance / time

------------------------------

Total Distance

speed = 62

time = 5

62 * 5 = 310 miles

Distance travelled in first 2 hours

speed = 50

time = 2

50 * 2 = 100 miles

Remaining distance

310 - 100 = 210 miles

Speed to cover 210 miles in 3 hours

distance = 210

time = 3

210/3 = 70 miles per hour

Step-by-step explanation:

Data show that men who are married, and also divorced or widowed men, earn quite a bit more than men the same age who have never been married. This does not mean that a man can raise his income by getting married because men who have never been married are different from married men in many ways other than marital status. Suggest one possible lurking variable that might help explain the association between marital status and income.
Choose the most plausible suggestion from the choices.
A. Men who are married, widowed, or divorced are usually more committed both in their personal and professional lives, enabling them to succeed in their careers.
B. Married, widowed, or divorced men have high income jobs. A high income job tends to make an individual more dedicated. This dedication leads a man to get married.
C. High income leads to greater commitment, which leads to marriage. Thus, we see that high income should actually be associated with men who have never been married.
D. Married, widowed, or divorced men tend to be more committed as well as men with high income jobs. From this, we may safely conclude that getting married leads to a high income job.

Answers

Answer:

B. Married, widowed, or divorced men have high income jobs. A high income job tends to make an individual more dedicated. This dedication leads a man to get married.

Step-by-step explanation:

A lurking variable is one that is not measured in the given study but it will affect the relationship between the explanatory and response variables.

Now, in this case, we see that divorced or widowed men, are said to earn quite a little more than men that are of the same age who have never been married.

Now, we are told it does not imply that a man can raise his income by getting married.

This means that majority who have high income tend to consider getting married.

Thus, we can infer that having a high income job leads to a man being more dedicated and this leads him to getting married.

Answer:

KL = 23

KM = 29

Step-by-step explanation:

By applying cosine rule in the given triangle KLM,

cos(∠M) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(52°) = [tex]\frac{LM}{KM}[/tex]

cos(52°) = [tex]\frac{18}{KM}[/tex]

KM = [tex]\frac{18}{\text{cos}52}[/tex]

KM = 29.24

KM ≈ 29

By applying sine rule,

sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(52°) = [tex]\frac{KL}{29.24}[/tex]

KL = 29.24[sin(52°)]

    = 23.03

    ≈ 23

KL = 23

which three fractions are less than 40%

A. 3/20
B. 23/100
C. 3/5
D. 1/8​

Answers

Answer:

A, B, D

Step-by-step explanation:

Answer:

A, B, D

Step-by-step explanation:

40% is the same as the fraction 4/10.

Compare 4/10 with 3/20 (A):

LCM of 10 and 20 is 20, so make the denominators of all fractions to 20

We now have 8/20 and 3/20

Now you can just simply look at the numerators. 3 is obviously less than 8 so option A is less than 40%

Compare 4/10 with 23/100 (A):

LCM of 10 and 100 is 100, so make all denominators 100

Now compare 40/100 and 23/100

40>23 so 23/100 is less than 40%

Compare 4/10 with 3/5 (C):

We can further reduce 4/10 to 2/5, and conveniently it has the same denoninator as 3/5. 3 is NOT less than 2, so C is ruled out.

Compare 4/10 with 1/8 (D):

LCM of 10 and 8 is 40, so we'll use that as our denominator

We now have 16/40 and 5/40.

5 is less than 16, so we include D in our answer.
