Answer:
C
Step-by-step explanation:
The weak law of numbers says that the more times you do an experiment, the closer you will get to the theoretical probability
Answer:
y=3x+1
Step-by-step explanation:
First, you need to find the slope. With the two points you can find the slope by subtracting one point from the other. This gives you a slope of 3. You could plot this on a graph to get the +1, or you can just look at these two points. (0,1) just gives it to you because this point is on the line.
The null hypothesis to test the significance of the slope on a regression equation is that the slope is equal to zero.
Given that we have to test the significance of slope in a regression equation.
Equation is relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be a linear equation, quadratic equation, cubic equation or many more depending on the powers of the variable present in that equation.
Slope is basically a number which indicates the direction of the line.
Null hypothesis is a statement which is tested for its validity and it is nothing but opposite of the result we want.
The standard regression equation be y=mx+c and in this m is slope of the equation.
The line depends on the slope because if it is zero then the value of y becomes zero. So, the null hypothesiss is that the slope is equal to zero.
Hence the null hypothesis to test the significance of the slope on a regression equation is that the slope is equal to zero.
