H0: Lot A tensile strength is not greater than lot B tensile strength

H0: Lot A tensile strength exceeds or equal lot B tensile strength

H0: Lot A tensile strength is comparable to lot B tensile Strength

1. H1: The mean of Lot A tensile strength is < the mean of Lot B tensile strength.

2. H1: The mean of Lot A tensile strength is > the mean of Lot B tensile strength.

3. H1: The mean of Lot A tensile strength =/ the mean of Lot B tensile strength

Answer #1

The correct null and alternative hypotheses are,

A)

H0: Lot A tensile strength is not greater than lot B tensile strength.

H1: The mean of Lot A tensile strength is > the mean of Lot B tensile strength.

B)

H0: Lot A tensile strength exceeds or equal lot B tensile strength.

H1: The mean of Lot A tensile strength is < the mean of Lot B tensile strength.

C)

H0: Lot A tensile strength is comparable to lot B tensile Strength.

H1: The mean of Lot A tensile strength =/ the mean of Lot B tensile strength.
