"in Original Source 2, Development and initial validation of the Hanguver Symptoms Scale prevalence and correlates of hangover symptoms in college students, one or the questions was how many times respondents had experienced at least one hangover symptom in the past year. Table 3 ofthe paper (page 1.445) shows that out of all 1,215 respondents, 40% answered that it was two orfewer times. Suppose the researchers are interested in the proportion of the population who would answer that it was two or fewer times can they conclude that this population proportion is significantly less than half (50% or 0.5) Go through the four steps of hypothesis testing tor this situation for women only (n = 749; null hypothesis C- The population proportion of college women who experienced at least one hangover symptom two or fewer times in the past year is less than one half. The population proportion of college women who experienced at least one hangover symptom two or fewer times in the past year is one half. The population proportion of college women who experienced at least one hangover symptom two or fewer times in the past year is greater than one half. of alternatiye hypothesis The population proportion of college women who experienced at least one hangover symptom two or fewer times in the past year is less than one half.
