U B 2 A. A From the StudentSurvey dataset, we have the frequency counts for whether or not students smoke and also the gender of the student. The results are shown in the following table: Smoke Don't smoke Total Female 16 153 169 Male 27 166 193 Total 43 319 362 This is a hypothesis test so our goal is to find out how extreme the data are, if the null hypothesis is true. The null a hypothesis for this test is that smoking status and gender are not related. In other words, the same percentage of males and of females should be in each of the categories: smoke and not smoke. We find the expected counts by forcing those percentages to be the same. of all 362 students: What percent are smokers? What percent are non-smokers? How many females are in the study? Multiply the overall percent of smokers by the number of females to get the expected count for female smokers: Multiply the overall percent of non-smokers by the number of females to get the expected count for female non- smokers: How many males are in the study? Multiply the overall percent of smokers by the number of males to get the expected count for male smokers: Multiply the overall percent of non-smokers by the number of males to get the expected count for male non- smokers: Put your results in the table below.
