The p-value is
O Less than (or equal to) a
O Greater than a
The p-value leads to a decision to
O Accept Ho
Do Not Reject Ho
O Reject Ho
The conclusion is
There is a significant linear correlation between advertising expense and profit.
O There is insufficient evidence to make a conclusion about the linear correlation between advertising
expense and profit.
There is a significant positive linear correlation between advertising expense and profit.
O There is a significant negative linear correlation between advertising expense and profit.
