The table below represents the closing cost of abc for the last 5 days. what is the r -value of the linear regression that fits these data? day value 1 20.712 19.693 19.614 19.645 19.26choices are as follows a. -0.79631b. 0.86493c. 0.91237d. -0.85650

The correct option is D.

Step-by-step explanation:

The linear regression equation is in the form of

Where,

The formula of r is

The values are

Using above formula, we get

Therefore option D is correct.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
