'For tasks 1 to 5, you are going to explore the relationship between a baby's weight at birth and their weight at 5 weeks. You're interested in answering the following question: "Can the weight of a baby at birth (in kg) be used to linearly predict the weight of the baby (in kg) at 5 weeks?" Use the dataset to examine if this is a linear relationship, and if it is, is it significant, and what does the linear relationship look like (i.e. define the equation of the line between these two variables).'

1. What type of variable (quantitative or qualitative) is the independent variable (IV)? If it is qualitative, state the number of levels (categories) in the variable.

2. What type of variable (quantitative or qualitative) is the dependent variable (DV)? If it is qualitative, state the number of levels (categories) in the variable.

3. What is the null hypothesis for the correlation between the IV and the DV? Write this in words only.

4. What is the null hypothesis for the slope of the regression line for the IV and the DV? Write this in words only.

5. What is the overall null hypothesis for this research question
