The altitude in thousands of feet and speed of a plane in fe

The altitude (in thousands of feet) and speed of a plane (in feet per second) for various altitudes is shown below compLetes part a through Display the date in scatter plot. Choose the correct graph below Calculate the correlation coefficient r r = (Round to three decimal places as needed) Make a conclusion about the type of correlation The correlation is a linear correlation

Solution

1) Option A is the scatter plot for the data given.

2) Correlation coefficient = -0.389 as shown below:

?X=140 , ?Y=8229.8 , ?X?Y=142168 , ?X²=3500 , ?Y²=8487822.44

---------------------------

c) The correlation is a negative linear correlation.
