Question
Use chi-square method
1) Standing outside of the SURC, are you equally likely to see someone wearing sweatshirt, long sleeved shirt, or short sleeved shirt? We believe that you would be more likely to encounter someone wearing a sweatshirt, so we predict that the distribution will be different from what chance would predict. a) Describe the null and alternative hypotheses (hint: do not use directional hypotheses): b) You went to the SURC to observe people and counted how many people were wearing each color of shirt. The data are presented in the following table. First, identify the appropriate inferential statistic and test needed to answer our research question. Then, complete the table with all the required information you need, including expected values. Be sure to show all of your work: Observed Expected Sweatshirt 23 Long-sleeved 8 Short-sleeved 11 Total ineupoaduz brisapitalista leitmotoini bas avitqhozeb art jedw abrow ni ashemmuz (e songnettib & 21 sarit lig.s) noliasup lenigho nuo tuode zu flet gnitest zizarsogyri (519,ad of mes2 11 29ch enerw

c) Calculate the appropriate inferential statistic needed to answer our research question. Be sure to show all of your work: d) 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: beseda 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, etc.):
