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.

777dan777 [17]
Answer:
The range is 10
Step-by-step explanation:
To find the range you need to find the lowest number in value, and subract it from the highest number in value.
If it was bought after 10% discount, it means it was bought at 90% of the original price:
90% = $450
1% = $5
100% = $5 x 100
100% = $500
The original price of the Play Station was $500.
Answer:
m=-29/3 and n=65/3
Step-by-step explanation:
The given system has equations:
3m+3n=36
8m+5n=31
Multiply the top equation by 5 and bottom equation by 3 to get:
15m+15n=180
24m+15n=93
Subtract the top equation from the bottom equation to get:
9m=-87
Divide both sides by 9
We substitute this value into the first equation to get:
