Final answer:
It is not possible to answer the questions without specific data provided.
Step-by-step explanation:
a. Decide which variable should be the independent variable and which should be the dependent variable.
The independent variable is the one that is manipulated or changed in an experiment. The dependent variable is the one that is measured or affected by the independent variable. In this case, it is not clear which variables are being referred to, so it is difficult to determine which should be independent and which should be dependent.
b. Draw a scatter plot of the data.
Without specific data provided, it is not possible to draw a scatter plot.
c. Does it appear from inspection that there is a relationship between the variables? Why or why not?
Without specific data provided, it is not possible to determine if there is a relationship between the variables.
d. Calculate the least-squares line. Put the equation in the form ý = a + bx.
Without specific data provided, it is not possible to calculate the least-squares line.
e. Find the correlation coefficient. Is it significant?
Without specific data provided, it is not possible to find the correlation coefficient.
f. Find the estimated average height for a 1-year-old. Find the estimated average height for an 11-year-old.
Without specific data provided, it is not possible to find the estimated average height for a 1-year-old or an 11-year-old.
g. Does it appear that a line is the best way to fit the data? Why or why not?
Without specific data provided, it is not possible to determine if a line is the best way to fit the data.
