Question

In a Quinnipiac University Poll of registered voters nationwide taken in June of 2007, 43% of those

polled blamed oil companies the most for the recent increase in gasoline prices. A local politician

believes that the percentage of voters in his district is actually greater than 43%. Describe the

consequence of a Type II error in context.

A) Concluding that the local percentage is higher than 43% when it is actually not significantly

different from 43%.

B) Concluding that the local percentage is not different from 43% when it actually is lower.

C) Failing to collect a large enough random sample to conclude that the local percentage is over

43%.

D) Concluding that the local percentage is not different from 43% when it actually is higher.

E) Failing to make the correct decision because the calculated P-value was incorrect.

Type II error occurs when a Null Hypothesis is accepted when it is false.

Here, cases A,B and D have type II errors.
