Interstate Speeds

11.       Tornado Deaths A researcher claims that the standard deviation of the number of deaths annually from tornadoes in the United States is less than 35. If a sample of 11 randomly selected years had a standard deviation of 32, is the claim believable? Use a = 0.05.

Source: National Oceanic and Atmospheric Administration.

 

12.        Interstate Speeds It has been reported that the standard deviation of the speeds of drivers on Interstate 75 near Findlay, Ohio, is 8 miles per hour for all vehicles.

A driver feels from experience that this is very low.

A survey is conducted, and for 50 drivers the standard deviation is 10.5 miles per hour. At a = 0.05, is the driver correct?
