Question

Please help.

4. Maria also wants to study the relationship between the way of puppies at birth and their adult weight at 2 years old she collected data from five randomly so like a small breeds dogs and display the data on the table.

Part C:perform a linear regression and interpret the results

A. Use a calculator to perform a linear regression. Round The valleys your calculator gives you for A and b to the nearest hundredth.

B. What is the slope of the regression equation? What does this mean in terms of the birth weight and adult weight?

C. What is the value of the correlation coefficient?

Answer 1

Hello! The answers will be in explanation :D

Explanation:

a) You can use a linear regression calculator online to get the equation. You would get the equation: y = 4.87x + 2.28

b) The slope would be 4.87, m is the slope in the slope-intercept equation. The slope represents that for each puppy that is at birth, their adult weight adds 4.87 pounds each time.

c) The value of the correlation coefficient is 0.989. Again, you could always search up a correlation coefficient calculator online and get the same solution I have.

Hope this helps! ^^

Answer 2

Part C. Perform a linear regression and interpret the results.

a. Use a calculator to perform a linear regression. Round the values your calculator gives you for a and b to the nearest hundredth. (2 points)

y = ___4.87____x + ____2.28___

b. What is the slope of the regression equation? What does this mean in terms of birth weight and adult weight? (2 points)

The slope of the regression equation is 4.87. This means that as the puppies get older they will get heavier at a rate of 7.87

c. What is the value of the correlation coefficient? (1 point)

The Correlation coefficient has a value of 0.989
