Given your response to part b, which means significantly differ? Population Mean Ditterences Can we conclude that the population means differ? u1-u3 - Before the Great Recession, Job-creating cities in the Sunbelt, like Las Vegas, Phoenix, and Orlando saw their populations, income levels, and housing prices surge. Las Vegas, however, offered something that often eluded these other cities: upward mobility for the working class. For example, hard-working hotel maids were able to prosper during the boom times. According to the Bureau of Labor Statistics, the average hourly rate for hotel maids was $14.25 in Las Vegas, versus $9 25 in Phoenix and $8.84 in Orlando (The Wall Street Journal, July 20, 2009). Suppose the following summary statisties and ANOVA table were produced for a = 005 from a sample of hourly wages of 25 hotel maids in each city Groupa Las Vegaa Phoenix Orlando SUMMARY Count 25 25 25 Average 13.91 0.82 8.03 AHOVA Source of Vaiation Betveen Groupa Within Groups SS 430.07 76.44 507.31 dr 215.44 1.06 202.90 Pvalue 2.SeE-30 Total 74 b.
