Reconsider the previous two exercises.
a. Use a theory-based method to determine the test statistic and p-value.
b. Investigate and comment on whether the validity conditions of the theory-based method are satisfied.
c. Does the p-value obtained using the simulation-based method agree with that obtained using the randomization/ simulation-based method?
d. Summarize your conclusion from this study, addressing whether the data provide strong evidence to support the students’ conjecture.

Data from previous questions|

Student researchers investigated whether balsa wood is less elastic aft er it has been immersed in water. They took 44 pieces of balsa wood and randomly assigned half to be immersed in water and the other half not to be. They measured the elasticity by seeing how far (in inches) the piece of wood would project a dime into the air.
