An exercise physiologist is studying energy exertion from playing video games. Participants first play Wii bowling for 15 minutes, during which researchers measure calories burned. After a period of rest, participants then play Will tennis. The average change in energy expenditure scores was 12 points, and a paired-samples t test gave a probability value of .09 (9%). Which of the following interpretations is correct regarding these results?
Select one:
a. There is a 9% probability that the null hypothesis is true in the population
b. If there is truly no difference in the population, a change of 12 points or more would occur in 9% of all random samples from such a population
c. If there is truly a difference in the population, an increase of 12 points or more would occur in 9% of all random samples from such a population
d. A difference of 12 points has a 9% probability of occurring due to random chance
