Answer
P-value $\ltα$
There is enough evidence to conclude that a linear relation exists between total length and weight.
Work Step by Step
In MINITAB, enter the Total Length values in C1 and in C2 enter the Weight values.
Select Stats -> Regression -> Regression -> Fit Regression Model
Enter C2 in "Responses" and C1 in "Continuous Predictors"
P-value $=0.011\ltα=0.05$
