Alcoholics tend to consume more alcohol than do others, although that does not define Alcoholism.
No, there is not a correlation.
partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
There is no correlation.
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).
correlation implies the cause and effect relationship,, but casuality doesn't imply correlation.
Positive correlation has a positive slope and negative correlation has a negative slope.
Yes. There is a real correlation between HPV and oral cancers
A serious error. The maximum magnitude for a correlation coefficient is 1.The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them. Here they are given less than -1 value so it is not a value of correlation coefficient.
There is no line that shows the correlation between two data sets. The correlation is a variable that ranges between -1 and +1.You may be thinking about regression which, although related, is not the same thing.There is no line that shows the correlation between two data sets.

If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
Why the value of correlation coefficient is always between -1 and 1?
a zero correlation means that there is no relationship between the two or more variables.
