Answer:
<h2>Jordan age = 31 years</h2><h2>Anna age = 19 years</h2>
<u>Step-by-step explanation:</u>
let Jordan age be <u>X</u> & Anna age be <u>Y</u>
so,
Jordan is 12 years older than Anna.
x = y + 12 ......... (1)
The sum of their ages is 50.
x + y = 50 ........ (2)
putting value of x from (1) into (2)
x + y = 50
(y + 12) + y = 50
2y + 12 = 50
2y = 50 - 12
2y = 38
y = 38÷2
y = 19
putting value of y in (2)
x + y = 50
x + 19 = 50
x = 50 - 19
x = 31
so,
Jordan age = 31 years
Anna age = 19 years
Answer:
A. False,
B. False,
C. True.
Step-by-step explanation:
We have been given three statements about the correlation. We are asked to determine which of the given statement are true.
(A) A correlation of 0.02 indicates a strong positive association.
We know that a correlation coefficient close to 1 represents positive association and a correlation coefficient close to 0 represents negative association.
Since our given correlation coefficient is close to 0, therefore, it represents negative association and given statement is false.
(B) Standardizing the variable will make the correlation 0.
We know that standardizing the variable does not change the correlation.
If correlation between the variables was 0, then the correlation between standardized variables also will be 0. Therefore, the given statement is false.
(C) Adding an outlier can dramatically change the correlation.
We know that correlation is strongly influenced by outliers, therefore, the given statement is false.
