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 Saved Question 9 (1 point) O
