Question

Given the following null and alternative hypotheses, conduct a hypothesis test using an alpha equal to 0.05. (Note: The population standard deviations are assumed to be known.)

H0: µ1 ≤ µ2

HA: µ1 > µ2

The sample means for the two populations are shown as follows:

sample mean 1 = 144,  sample mean 2 = 129

population standard deviation 1 = 11,  population standard deviation 2 = 16

sample size 1 = 40, sample size 2 = 50

Answer: 


Decision Rule : Reject H0 if  Zcal > citical value Z =  
Test statistic: (Z calculated) Zcal =    (use 4 decimal places)
Conclusion:    H0.
