Problem 3.48

Referring to Exercise 3.39, nd (a) f(y|2) for all values of y; (b) P(Y =0| X = 2).

Step-by-Step Solution:

Step 1 of 3

Simple Linear Regression  Analyzing relationship between 2 variables  X= hours studied Y=test score  Response variable (y)= dependent variable  Explanatory variable (x)= independent variable o Helper o Helps estimate mean of y’s  Scatterplot used to identify o Patterns/ relationships o Outliers  What regression line gives you o Line of means for y population o Prediction of the mean o Value of the regression equation is the “least squares” estimate of the mean of that y subpopulation  Include units!! sample correlation coefficient, r  Measures the strength of the LINEAR association between 2 quantitative variables  P= population corr
