Hypothesis test results:
μ1 : Mean of var1 (Std. dev. not specified)
μ2 : Mean of var2 (Std. Dev. not specified)
μ1 - μ2 : Difference between two means
H0 : μ1 - μ2 = 0
HA : μ1 - μ2 ≠ 0
Difference n1 n2 Sample mean Std. err. Z-stat P-value
μ1 - μ2 15 15 -13.6 3.3397082 -4.0722121 <0.0001
I am having a problem trying to figure out how to conclude and I want to make sure I am correct so far in my answer.
