These are two hypotheses with the two samples drawn independently from 2 normally distributed distributions.

  • Ho: µ 1- µ2= 0
  • Ha: µ 1- µ2 not equal to 0

sample #1 mean = 67

sample #2 mean = 69

sample #1 population var = 17

sample #2 population var = 15

n1= 30

n2=35

Test whether the population means differ at the 1% significance level. Tell us the result of the hypothesis.
