pothesis Testing with the p-value Method The mayoral challenger claims that less than 30% of residents over the age of 25 have bachelor's degrees in our city. To test this claim, you survey 80 adults over the age of 25 and find only 18 possess bachelor's degrees. At the 5% level of significance, is there enough evidence to SUPPORT the challenger's claim? 1.) Is this a hypothesis test for mean or proportion? If it's a test for mean, do we know the population standard deviation? 2.) Based on your answer in #1, which calculator will you use: A.) Mean -o Known, B.) Mean -a Unknown or C.) Proportions 3.) Will we use a Z-test or t-test? How do you know? 4.) What is the direction of the tail? Left, right or two?
