- 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
