When our brains store information, complicated chemical changes take place. In trying to understand these changes, researchers blocked some processes in brain cells taken from rats and compared these cells with a control group of normal cells. They report that "no difference was seen" between the two groups (P 0.45).
Say clearly what the P-value, P- 0.45, says about the response that was observed.
A) None of the options are correct.
B) P-0.45 says that a response this large or larger would be seen in sample data nearly all of the time when in fact there is no effect in the entire population of rats. That is, a response this size would often happen just by chance.
C) P-045 says that a response this large or larger would be seen in sample data almost half the time when in fact there is no effect in the entire population of rats. That is, a response this size would often happen just by chance
D) P-045 says that a response this small or smaller would be seen in sample data almost half the time when in fact there is no effect in the entire population of rats. That is, a response this size would often happen just by chance.
