In Ch 8 of your textbook there is a StatCrunch data set that notes whether or not a person

retired after age 65. YES means they did.

(The data set is in Ch 8 / "Retire After 65")

Suppose

it is reported that half

of all Americans retire after 65. You disagree - what do

you think the Ha direction should be here, >, <, or not equal to? Using your Ha, do the

hypothesis test and find out what happens. Is there enough evidence to say you're right?

Do steps a-f from the above problems.
