2) We conducted the previous study at night, right before a basketball game. We decided to also collect data during the day. Using the extra data collected, we want to attempt to again identify if standing outside of the SURC, you are equally likely to see someone wearing a sweatshirt, long sleeved shirt, or short sleeved shirt, and if that distribution depends on the time of day. a) Describe the null and alternative hypotheses (hint: do not use directional hypotheses): b) The original data along with the newly collected data are presented in the following table. Day-Observed Day-Expected Night - Observed Night-Expected Total Sweatshirt 13 16.62 23 19.38 36 Long sleeved Short sleeved shirt 14 10.15 8 11.85 22 shirt 9 9.23 11 10.77 20 Total 36 42 Identify the appropriate inferential statistic and test needed to answer our research question. c) What is the formula for the appropriate inferential statistic needed to answer our research question?

d) Imagine that the calculated Chi Square statistic = 4.19. Calculate the degrees of freedom (show all your work!) and use an alpha of .05 to determine whether or not the inferential statistic is statistically significant. Report the critical value you identify, and report the statistic in APA style: e) Summarize in words what the descriptive and inferential statistics, and subsequent hypothesis testing, tell us about our original question (e.g., if there is a difference, where does it seem to be, is there a dependency, etc.):
