#1. A company that sells a motorcycle ramp for loading a motorcycle onto a truck bed claims that the mean capacity is 1000 pounds. A random sample of 34 motorcycle ramps was obtained, and a destructive test was used to determine the capacity of each (in pounds). The sample had a mean capacity of 989.2 pounds with a standard deviation of 15.8 pounds. Is there sufficient evidence to suggest that the true mean capacity of this type of motorcycle ramp is less than 1000 pounds? Use = 0.05.
