Question

Hgt = height in inches, Age = age in years of a child. The data point is a child 12 years old who is 60 inches tall. Two variables are defined, a regression equation is given, and one data point is given. (a) Find the predicted value for the data point and compute the residual. (b) Interpret the slope in context. (c) Interpret the intercept in context, and if the intercept makes no sense in this context, explain why.

Two variables are defined, a regression equation is given, and one data point is given. (a) Find the predicted value for the data point and compute the residual. (b) Interpret the slope in context. (c) Interpret the intercept in context, and if the intercept makes no sense in this context, explain why. Study $=$ number of hours spent studying for an exam, Grade $=$ grade on the exam. $\widehat{\text { Grade }}=41.0+3.8$ (Study); data point is a student who studied 10 hours and received an 81 on the exam.

Two variables are defined, a regression equation is given, and one data point is given. (a) Find the predicted value for the data point and compute the residual. (b) Interpret the slope in context. (c) Interpret the intercept in context, and if the intercept makes no sense in this context, explain why. Weight $=$ maximum weight capable of bench pressing (pounds), Training = number of hours spent lifting weights a week. Weight $=95+11.7$ (Training); data point is an individual who trains 5 hours a week and can bench 150 pounds.

00:01 Hello, in this video i will be explaining the following.
00:04 So here we're just going to find the predicted value for the data points, and then the intercept, and then interoperate the intercept.
00:15 So for the height and age, i went ahead and found the numbers to put into it from the original question.
00:36 And if these are not your same numbers, just use this as a guideline.
00:45 So the hgt would just be 24 .3 plus 2 .6, 2 .76, which is our age for this.
00:56 So we must compare the predicted value of the real data point.
01:03 So here we're going to have our height equals 60 in age is going to be estimated at.
01:11 So now we just compute the predicted height.
01:28 24 .3 plus 2 .67.
01:38 And then you would just put the age, which is 12...
