Can you help me with this HW question?

A company produces an item that is supposed to have a 6-inch hole punched in the center. A quality control inspector is concerned that the machine that punches the hole is "out-of-control" (hole is too large or too small). In an effort to test this, the inspector is going to gather a sample punched by the machine and measure the diameter of the hole. The alternative hypothesis used to statistically test to determine if the machine is out-of-control is:

Question 5 options:

1)

the mean diameter is > 6 inches

2)

the mean diameter is < 6 inches

3)

the mean diameter is = 6 inches

4)

the mean diameter is ≠ 6 inches

5)

the mean diameter is ≥ 6 inches
