question 48

Multiple Choice

A truck company wants on-time delivery for 98% of the parts they order from a metal manufacturing plant. They have been ordering from Hudson Manufacturing but will switch to a new, cheaper manufacturer (Steel-R-Us) unless there is evidence that this new manufacturer cannot meet the 98% on-time goal. 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 hypothesis should they test?

• A) \( \mathrm{H}_{0}: p>0.98 \)
• \( \mathrm{H}_{A}: p=0.98 \)
• B) \( \mathrm{H}_{0}: p=0.98 \)
• \( \mathrm{H}_{A}: p<0.98 \)
• C) \( \mathrm{H}_{0}: p=0.98 \)
• \( \mathrm{H}_{A}: p>0.98 \)
• D) \( \mathrm{H}_{0}: p<0.98 \)
• \( \mathrm{H}_{A}: p>0.98 \)
• E) \( \mathrm{H}_{0}: p=0.98 \)
• \( \mathrm{H}_{A}: p \times 0.98 \)
