How do I set this up using the five step hypothesis testing procedure? How do you state your decision and recommendation without using statistical jargon.
The manufacturer of the X-15 steel-belted radial truck tire claims that the mean mileage the tire can be driven before the tread wears out is 60,000 miles. The standard deviation of the mileage is 5,000 miles. The Crosset Truck Company bought 48 tires and found that the mean mileage for their trucks is 59,500 miles. Is Crosset's experience different from that claimed by the manufacturer at the .05 significance level?© BrainMass Inc. brainmass.com June 3, 2020, 6:08 pm ad1c9bdddf
