Question: 3.We are testing hypotheses about p = the proportion of all drivers who admit to running red lights.After sampling 255 drivers, 133 admit to running
3.We are testing hypotheses about p = the proportion of all drivers who admit to running red lights.After sampling 255 drivers, 133 admit to running red lights. The sample proportion is p-bar= 133/255 = 0.52 and the test statistic from step 4 is Z = 0.64.
Ho: p=0.5 Ha: p 0.5
(1)Place p = 0.5 on the graph
(2)Placep-bar= 0.52 on the graph
(3)Shade the area which represents the P-value
(4)Find the P-value: _________
(5)Interpret the meaning of the P-value:Assuming p really is 0.5, there is a ______% chance of getting a sample proportion of p-bar = 0.52 or even __________ .
