Don’t you have to flip the sign when you divide by a negative? So I think she’s wrong bc the answer should be d is less than or equal to 7.5
The correlation coefficient for the data in the table was found to be 0.93.
The correct option is A.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient focuses on the linear relationship between two variables.
Given
The first column is labeled time spent at the dentist (in hours) with entries 1.4, 2.7, 0.75, 1.6.
The second column is labeled bill amount (in dollars) with entries 235, 867, 156, 215.
The numbers between -1 and 1 should be one of the values related to the bill.
Taking the independent variable or input variable as, the time a patient spends at the dentist and the dependent variable or output variable as the amount of the bill.
Hence, The correlation coefficient for the data in the table was found to be 0.93.
