Scenario 2: Perform a simple linear regression analysis to predict a newborn’s birth length (in inches) using the mother’s height as a predictor variable. Conduct your analysis using a 95% level of confidence.
Question 6: Does the regression model confirm a correlation between the dependent variable and the independent variable? How do you know? (5 points)
Question 7: Is the statistical significance of the model as a whole acceptable for a 95% level of confidence? How do you know? (5 points)
Question 8: Is the statistical significance of the linear relationship between the dependent and independent variable acceptable for a 95% level of confidence? How do you know?
Question 9: What is the regression equation for the model? (5 points)
Question 10: What is the predicted birth length of a newborn whose mother is 61.5 inches tall? (5 points)

Explanation / Answer
Question 6: Does the regression model confirm a correlation between the dependent variable and the independent variable? How do you know? (5 points)
the regression model confirm a correaltion between teh dependent variable and the indpeendnent variable
because R^2 is greater than 0.5
Question 7: Is the statistical significance of the model as a whole acceptable for a 95% level of confidence? How do you know? (5 points)
this is acceptable for 95% because the p value is greater than 0.05
