![Assume that you reject the null hypothesis of no-difference at a=0.05. This means
that if you assume that there is no difference in the population between weather and
purchasing behavior, and the probability of getting a sample that deviates as much
from the expected values as your sample does is less than 5%, you reject the null.
Then, as a statistics expert, you
Reject the null
Fail to reject the null
Wouldn't know what to do
Would flip a coin to decide
