Asimple linear regression model was used to describe the relationship between y 5 hardness of molded plastic and x 5 amount of time elapsed since the end of the molding process. summary quantities included n 5 15, ssresid 5 1235.470, and ssto 5 25,321.368.

a. calculate a point estimate of s. on how many de- grees of freedom is the estimate based?

b. what percentage of observed variation in hardness can be explained by the simple linear regression model relationship between hardness and elapsed time?

In the 10th grade, i was teamed up in a group of four. our project was on modern history. altho it seemed super hard for many of us. patrick fleming  took charge and showed us the understanding of this project.  his leadership showed great ethics and it taught me, personally, how to others understand, not just to show them, but explain it thoroughly. and altho he was a great teacher i would have changed a few things. one being his attitude. many times he would get frustrated and impatient with the group.  i think  a leader i would have done exactly  what he did but with much more patience and be there more to explain. such as lunch  learning. and giving everybody a chance to try to explain it in their  head. 

Ibelieve the answer is b. assetshope my answer has you : )

It’s important because your less likely to get a wrong answer from credible sources

Ahope i
