The table below gives the number of weeks of gestation and the birth weight (in pounds) for a sample of five randomly selected babies. Using this data, consider the equation of the regression line, y = bo + bịx, for predicting the birth weight of a baby based on the number of weeks of gestation. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant. %3D Weeks of Gestation 33 35 38 39 41 Weight (in pounds) 5.4 5.9 7.4 7.5

Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
Question
Transcribed Image Text:The table below gives the number of weeks of gestation and the birth weight (in pounds) for a sample of
five randomly selected babies. Using this data, consider the equation of the regression line, y = bo + bjx,
for predicting the birth weight of a baby based on the number of weeks of gestation. Keep in mind, the
correlation coefficient may or may not be statistically significant for the data given. Remember, in practice,
it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is
not statistically significant.
