Question

The table shows the time a patient spends at the dentist and the amount of the bill. A 2-column table with 4 rows. 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. What is the correlation coefficient for the data in the table? –0. 93 –0. 27 0. 27 0. 93.

Answer 1

The correlation coefficient for the data in the table was found to be 0.93.

The correct option is A.

What is the correlation coefficient?

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.
