Match the null hypothesis (H
0
) to the correct alternative
hypothesis (H
1
):
t A tensile strength is not greater than lot B tensile strength
t A tensile strength exceeds or equals lot B tensile strength
t A tensile strength is comparable to lot B tensile Strength
1 .
H
1
: The mean of Lot A tensile strength is < the mean of Lot B t
2 .
H
1
: The mean of Lot A tensile strength is > the mean of Lot B te
3 .
H
1
: The mean of Lot A tensile strength ≠ the mean of Lot B tens

design has greater than 37 mpg. If H0 is rejected, the action
