Solution :
Assuming
We have to test
Against
Level of significance,
= 420.6107
Under , the t-statistics is as follows:
= 0.90
DF = (25 + 20 - 2)
= 43
P-value of the test = 0.375
Since the p value is more than 0.05, we fail to reject our null hypothesis.
There is no difference between then mean tensile strength of the ropes that is produced in the Bozeman and Challis.
