Determine the value of the test statistic and the associated p-value

1.For the data set
(−2,2),(3,9),(5,10),(7,20),(9,25),
carry out the hypothesis test
H0:ρ=0
Ha:ρ≠0

Determine the value of the test statistic and the associated p-value.

Test Statistic = 

p-Value = 

2.Find the regression standard error and the coefficient of determination for the least-squares regression line yˆ=b0+b1x through the points
(−3,1),(2,9),(6,13),(7,20),(11,27).
Regression Standard Error s = 

Coefficient of Determination r2 =
