Hey I need help please. If a correlation coefficient is -0.9 what can you say about the data. Also this is a separate question but what does it mean for 2 sets of data to be positively correlated.
Answer:
Step-by-step explanation:
A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution. Pearson’s correlation coefficient returns a value between -1 and 1. The interpretation of the correlation coefficient is as under:
If the correlation coefficient is -1, it indicates a strong negative relationship. It implies a perfect negative relationship between the variables.
If the correlation coefficient is 0, it indicates no relationship.
If the correlation coefficient is 1, it indicates a strong positive relationship. It implies a perfect positive relationship between the variables.
A higher absolute value of the correlation coefficient indicates a stronger relationship between variables. Thus, a correlation coefficient of 0.78 indicates a stronger positive correlation as compared to a value of say 0.36. Similarly, a correlation coefficient of -0.87 indicates a stronger negative correlation as compared to a correlation coefficient of say -0.40.
Correlation Values
In other words, if the value is in the positive range, then it shows that the relationship between variables is correlated positively, and both the values decrease or increase together. On the other hand, if the value is in the negative range, then it shows that the relationship between variables is correlated negatively, and both the values will go in the opposite direction.

All of the following represent the same set of numbers except
positive integers
whole numbers
natural numbers
counting numbers
Let us define each :
1. Natural numbers : the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
2.Whole numbers: Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)
3. Positive integers: The positive integers, z+ , consist of the whole numbers beginning with one.
4. Counting numbers: Any number you can use for counting things: 1, 2, 3, 4, 5, ... (and so on). Does not include zero.
So we can say that whole numbers is the odd one out, since it includes 0 and others dont.
The answer is whole numbers because only whole numbers are the set that starts from zero.

Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below. Using complete sentences, make one inference comparing the two groups and explain your reasoning.
Sample #1
16 11 9 12 11
10 10 8 15 0
2 15 14 7 11
5 14 20 3 11
14 7 0 5 21
Sample #2
21 14 0 3 6
7 10 11 7 9
14 0 15 5 12
20 0 12 11 6
0 21 14 0 6
Answer:The data is pretty evenly distributed in the age 20-39 group.
There are no outliers in either age group.
The range of the two age groups is the same.
Both data sets contain about the same amount of variation.

Answer:
Its A : 1188
Step-by-step explanation:
Because you have two heights 5 and 6 so add them together

What is the sum of two numbers 9 and their difference is 7
14 POINTS!!!!
Answer:
8 and 1
Step-by-step explanation:
8 + 1 = 9
8 - 1 = 7
Answer:
Step-by-step explanation:
Let b>a
a+b=9 and b-a=7 upon adding these two equations together
a+b+b-a=9+7
2b=16
b=8, given a+b=9
a+8=9
a=1
So the two numbers are 1 and 8

Answer:
X=54
Step-by-step explanation:
There are multiple steps to find this problem:
So in a triangle, the opposite inverse angles are congruent,
meaning <LQM and <PLQ are congruent so <LQM is also 70 degrees
a triangle = 180 degrees, therefore, triangle QLM can be solved by adding
54 and 70 to find the measure of the 3rd angle
54+70= 124, then 180 (because its the total amount of the triangle) - 124= 56
Then, we know that <QLM and <PQL are congruent angles as they are opposite inverse angles.
So, <PQL also equals 56 degrees
Then to find the 3rd angle of the triangle PLQ you can add 56 and 70 to find the 3rd angle
56+70= 126, Then 180 - 126= 54
So, X=54
Three less than on-half a number is -71
Your Answer:
B. 1/2n-3
Explanation:
One way to get half a number is to multiply it by 1/2.
The phrase "a number less than an other number" often indicates subtraction.
Nathan is 3 years older than Olivia. Determine the equation if n represents the age of Nathan and o represents the age of Olivia.
A. n = o + 3
B. o = n + 3
C. n = 3o
D. o = 3n
Answer: A, n=o+3
Step-by-step explanation:
Nathan (n) is 3 years older than Olivia (o) so Nathan's age would equal Olivia's age plus 3 years.
