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?

Step-by-step explanation:

Given that a study on the relationship between the estriol levels of pregnant women and the birth weights of their children is given in the table.​ Here, x denotes estriol​ level, in​ mg/24 hr, and y denotes birth​ weight, in hectograms.

x y

15 33

25 39

21 34

18 33

27 44

12 25

19 35

16 32

r 0.943228963

r^2 0.889680876

Since r is near to 1, there is a good relation linear between x and y.

a) A. There is a linear pattern to the​ data, so it is appropriate to carry out a linear regression.

b) R^2 = 0.8897

c) The percentage of variation in the observed values of the response variable explained by the​ regression= 88.97

i.e. R^2represents the percentage of variation between the two variables.

d) C. Very useful, since here linear relation is strong.
