Multiple Choice

A truck company wants on-time delivery for at least 98% of the parts they order from a metal manufacturing plant.

As a test the truck company purchases a random sample of metal parts from Steel-R-Us, and then determines if these parts were delivered on-time. Which hypotheses should they test?

• A) H0: p < 0.98 HA: p > 0.98
• B) H0: p > 0.98 HA: p = 0.98
• C) H0: p = 0.98 HA: p < 0.98
• D) H0: p < 0.98 HA: p ≠ 0.98
• E) H0: p = 0.98 HA: p > 0.98
