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.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
