Pls someone help I really need these answers fast

Using the graphing calculator, type in the table and complete a linear regression. The value of the correlation coefficient is found next to the letter (__) in the table. The value of the correlation coefficient is (__) [round to the hundredths place]. When the correlation coefficient is interpreted, it means that the correlation is (__) and (__). This means the points will be (__) [close or further away] to the line.

 

The table shows the heights and the lengths of several rectangles.
Height (in.) 41 70o 21 34 10 92 54 24 10 35 42 66
Length (in.) 21 25 32 12 16 45 40 23 45 35 21 14
What does the correlation coefficient for the data indicate about the strength of the linear
association between the height and the length of these rectangles?
