ANSWER BITH QUESTIONS!!!!!!!!!!!!
Consider the following table in reference to the testing of a null hypothesis:
Which of the following is incorrect?
Question 1 options:
Entries (1) and (4) are correct decisions.
The P(making entry (2)) is controlled by the sample size for a given alpha level.
A Type I error occurs if entry (3) occurs.
Power refers to P(entry (4))
A Type II error occurs when entry (1) is made.
Suppose Graph I gives the scatterplot relating data set X with data set Y, and Graph II gives the scatterplot relating data set G with data set H. The correlation coefficient relating data set X and data set Y is 0.958, and the correlation coefficient relating data set G and data set H is - 0.944. Which of the following statements will most likely describe the difference between Graph I and Graph II?
Question 15 options:
The patterns of the points in both graphs will actually be similar.
The points in Graph I will lie in an approximate straight line with positive slope, whereas the points in Graph II will lie in an approximate straight line with negative slope.
The points in Graph I will lie in an approximate straight line, whereas the points in Graph II will lie in an approximate circle
The pattern of the points in both graphs will be very scattered, whereby the patterns cannot be compared.

Explanation / Answer
Solution:-
15) The points in Graph I will lie in an approximate straight line with positive slope, whereas the points in Graph II will lie in an approximate straight line with negative slope.
The correlation coefficient relating data set X and data set Y is 0.958
Positive correlation is a relationship between two variables in which both variables move in tandem. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases. In statistics, a perfect positive correlation is represented by 1.
the correlation coefficient relating data set G and data set H is - 0.944
Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1.00,
