Ho: Mean salary = 45 Ho: Mean salary = 45 Ha: Mean salary =/= 45 Ha: Mean salary =/= 45 Note when performing a one sample test with ANOVA, the second variable (Ho) is listed as the same value for every corresponding value in the data set. t-Test: Two-Sample Assuming Unequal Variances t-Test: Two-Sample Assuming Unequal Variances Since the Ho variable has Var = 0, variances are unequal; this test defaults to 1 sample t in this situation Male Ho Female Ho Mean 52 45 Mean 38 45 Variance 316 0 Variance 334.6666667 0 … Observations 25 25 Observations 25 25 … Hypothesized Mean Difference 0 Hypothesized Mean Difference 0 df 24 df 24 t Stat 1.968903827 t Stat -1.913206357 P(T<=t) one-tail 0.03030785 P(T<=t) one-tail 0.033862118 t Critical one-tail 1.71088208 t Critical one-tail 1.71088208 P(T<=t) two-tail 0.060615701 P(T<=t) two-tail 0.067724237 t Critical two-tail 2.063898562 t Critical two-tail 2.063898562 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 I have computed the single factor ANOVA test which is shown below SUMMARY Groups Count Sum Average Variance Column 1 10 422.834608 42.2834608 9543.684155 Column 2 10 423.63016 42.363016 10745.73361 ANOVA Source of Variation SS df MS F P-value F crit Between Groups 0.031645148 1 0.031645148 3.11937E-06 0.998610224 4.413873419 Within Groups 182604.7599 18 10144.70888 Total 182604.7915 19 My text book is confusing me on how the information is to be interpreted. I am not looking for the answer, I am simply looking for someone to explain to me how I need to go about interpreting the information because as I previously stated, my textbook confuses me. So if someone would be willing to simply explain to me how I would go about interpreting the information (NOT GIVE ME THE ANSWER) it would be a huge help. Thank you in advance! |
