Question: Use the given data to find if there is a linear correlation given a 0.01 level of significance. If there is a correlation, then is it a positive or negative correlation? Determine the equation of the regression line. (Round values to 3 decimal places if necessary) Extra Credit on this next part: Determine the confidence interval for this problem. Of course you will need an x₀ value. So let x₀ = 6 for the confidence interval portion.

x 1 2 5 7 9

y 143 116 100 98 90
