b. p-value

less than 0.01

between 0.01 and 0.025

between 0.025 and 0.05

between 0.05 and 0.1

greater than 0.1

Conclusion

Because is p-value is (greater than or equal to, less than or equal to, equal to) 0.05, we (accept, reject) H0: B1 (greater than or equal to zero, less than or equal to zero, equal to zero)
