one tailed or 2 tailed for last blank.
![David McCandless, Lee Byron, and their team scanned more than 10,000 Facebook status updates and set out to learn more about the timing of
relationship breakups. They found that there was a peak in breakups on Valentine's Day and Mondays with a dip on Christmas Day. [Source:
McCandless, D. (July 2010). The beauty of data visualization. TEDGlobal talks.]
Suppose you are a researcher. You conduct a hypothesis test to determine whether the mean number
breakups on Wednesdays is greater than the
mean number of daily breakups. Assume that the mean number of daily breakups is 10.3 breakups (the population mean). You obtain a sample of
10,000 Facebook status updates, which yields a sample mean of M = 11.4 breakups.
Let u denote the mean number
breakups on Wednesdays. Formulate your null and alternative hypotheses by selecting the appropriate values in the
blue dropdown menus that follow.
