Two sample T test by hand, what do I do next? (n1 = 13 and n2 = 15)
sample mean 1: 2958.75
sample mean 2: 3361
variance 1: 261.05
variance 2: 334.20
tstat: -3.57
standard error: 112.64
t distribution: 25.75
These are the values I have so far, if someone could finish the t-test for me without using a software and explain I'd really appreciate it.
Above problem is solved using two sample t test.
As hypothesis is not given, we have used two sided test.
Level of significance is not given so we assume it default value 0.05, alpha = 0.05
Here equal variance is assumed because 1st varince is not double of 2nd variance.
Dear student,
