Many people believe that there is a “Friday effect” in the stock market. They do not necessarily spell out exactly what they mean by this, but there is a sense that the stock prices tend to be lower on Fridays than on other days.


Because stock prices are readily available on the web, it should be easy to test this hypothesis empirically. (SEE ATTACHED FOR MY TWO COMPANY DATA FOR 52 WEEKS-I already did this all and I summarized the data needed. Just need help answering questions.

  1. Before collecting data and running test, however, you must decide exactly which hypotheses you want to test because there are several possibilities. Formulate at least two sets of null/alternative hypotheses.
  2. Decide on criteria to support or refute your hypothesis.
  3. Conduct the test at different significance levels and discuss your findings. Can you conclude that there is a statistically significant Friday effect in the stock market?
