Newton’s 1st law is the answer because it states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
The correct answer is option A. 1,18.
Linear regression is a method used to identify the trend Or similarity between two sets of data. All the given points of the data set are plotted and a straight line is drawn with the points. The line is called a line of regression.
F Test is a test that is used to check if the given line of regression is a good fit for the given data set or not. F ratio is the ratio obtained by dividing the two mean square values of the data set.
The numerator of the given regression is always 1
The denominator of the regression is given by n-2=20-2=18.
