1. Conduct a hypothesis test for the following scenario. SHOW ALL YOUR WORK THE WAY WE DID IN CLASS!
Construction zones on highways have a much lower speed limit. To see if drivers obey these lower speed limits, a police officer uses a radar gun to measure the speed in miles per hour of a random sample of 10 drivers in a 30 mph speed zone. Here are the data:
26 28 32 21 27 31 29 22 25 34
Is there convincing evidence at the α = .05 level that the average speed is below the speed limit?

knov · Answer

to find out the average speed sum up the all data and divide it by it's number.
