Step-by-step explanation:
Given that in an inertia welding experiment, a sample of 50 welds made with a standard welding method were tested.
Group Group One Group Two
Mean 94.000 96.000
SD 3.000 3.500
SEM 0.424 0.452
N 50 60
The mean of Group One minus Group Two equals -2.000
standard error of difference = 0.629
t = 3.1818
df = 108
a) 95% confidence interval of this difference: From -3.246 to -0.754
b) Yes, there is evidence that there exists a difference in the true mean breaking strengths for the two types of welds. This is because confidence interval does not contain 0
