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 hypotheses
Should they test? A. $\quad H _ { 0 } : p < 0.98$
$H _ { a } : p > 0.98$

B. $H _ { 0 } : p > 0.98$
$H _ { a } : p = 0.98$

C. $H _ { 0 } : p = 0.98$
$H _ { a } : p < 0.98$

D. $H _ { 0 } : p = 0.98$
$H _ { a } : p \neq 0.98$

E. $H _ { 0 } : p = 0.98$
$H _ { a } : p > 0.98$
