  • Conduct a 5-step Hypothesis Test showing whether the population mean earnings of Hispanic women working FTYR differ from the population mean earnings of Hispanic men working FTYR.
    • Hispanic women mean = 59877.20
    • Hispanic women standard deviation = 60017.80
    • Hispanic women N = 242
    • overall women mean (including 3 other races) = 59456.88
    • overall women standard deviation (including 3 other races) = 59977.03
    • overall women N (including 3 other races) = 2,174 out of 5,000
    • Hispanic men mean = 59837.65
    • Hispanic men standard deviation = 60395.57
    • Hispanic men N = 401
    • overall men mean (including 3 other races) = 59465.83
    • overall men standard deviation (including 3 other races) = 59948.75
    • overall men N (including 3 other races) = 2,826 out of 5,000
    • Hispanic men and women N = 643 out of 5,000
    • Hispanic men and women mean = 59837.65
    • Hispanic men and women standard deviation = 60395.57
    • any other statistics or information needed?
  • Will the hypothesis test be a one-sample or a two-sample?
  • For the hypothesis test, determine whether the difference in sample mean earnings across the two groups is statistically significant:
    • At the 95% level and
    • At the 99% level
