A group of researchers tested whether snakes tend to choose a warm resting site when both a warm site and a cool site are presented to them. Their hypotheses were H₀ Snakes do not prefer the warmer site. H_A Snakes prefer the warmer site. They carried out the experiment and with their data calculated a one-tailed P-value  They rejected their null hypothesis and concluded that snakes prefer the warmer sites.

a. Is a one-tailed test appropriate here? Explain.

b. What would their hypothesis statements have been had they used a two tailed test instead?

c. What would their P-value have been had they used a two-tailed test instead?
