HELP BEST ANSWER

Answer 1

Answer:

The correct option is c.

Step-by-step explanation:

An experiment in a physics class involves dropping a golf ball and recording the distance in meters it falls for different times in sec.

The given data is

Time                          Distance

0                                  0

0.5                               1.2

1                                   4.9

1.5                               11.0

2                                19.5

2.5                            30.5

3                                44.0

The equation of  linear regression line is defined as

$y=a+bx$

The value of b is 14.657 and the value of a is -6.1143

The equation of linear regression line is

$y=14.657x-6.1143$

The value of R² is  0.9228.

Therefore option c is correct.
