Write the Hypotheses $H _ { 0 } : p = 0.28$

question 2

Short Answer

Write the hypotheses.
-A report on the U.S. economy indicates that 28% of Americans have experienced
Difficulty in making mortgage payments. A news organization randomly sampled 400
Americans from 10 cities named the "fastest dying cities in the U.S." (Forbes Magazine,
August 2008) and found that 136 reported such difficulty. Does this indicate that the
Problem is more severe among these cities? The correct null and alternative hypotheses
For testing this claim are A. $H _ { 0 } : p = 0.28$ and $H _ { A } : p > 0.28$
B. $H _ { 0 } : p = 0.28$ and $H _ { A } : p < 0.28$
C. $H _ { 0 } : p = 0.28$ and $H _ { A } : p \neq 0.28$
D. $H _ { 0 } : p \neq 0.28$ and $H _ { A } : p = 0.28$
E. $H _ { 0 } : p > 0.28$ and $H _ { A } : p = 0.28$

Definitions:

Overrunning Clutch

A drive-protection mechanism that prevents a drive member from being driven; for instance, after a starter motor has started the engine, the overrunning clutch prevents the engine from driving the starter and damaging it.

Flex Plate

A metal disc that connects the engine to the torque converter in automatic transmissions, allowing power transfer.

Driven Member

A component in a mechanical system that receives motion or power from another component, rather than generating it.

Centrifugal Lock-up

A mechanism in torque converters that locks the turbine to the pump when sufficient speed is achieved, improving fuel efficiency by eliminating slip.
