Final answer:
The statement implies a positive correlation between the weather forecast for wind and increased chapstick sales; it does not address whether chapstick is an inferior or normal good, nor directly relate to supply curve shifts.
Step-by-step explanation:
The statement 'More people purchase chapstick when the weatherman announces that we are in for a very windy week' suggests that the demand for chapstick increases with the expectation of windy weather, indicating a positive correlation between the weather forecast and the demand for chapstick. This is because people tend to buy more chapstick to protect their lips from becoming dry due to the wind. It does not directly speak to whether chapstick is an inferior good or a normal good. Those terms refer to how demand changes with income levels, not weather conditions. The supply-side effect mentioned, where good weather leads to an increase in quantity supplied and the supply curve shifts to the right, is not directly related to the statement in question.
