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 29 drivers the standard deviation is 9.9 miles per hour. At =α0.10, is the driver correct? Assume the variable is normally distributed. State the hypotheses and identify the claim with the correct hypothesis. H0: H1: Claim or Not a Claim? This Hypothesis test is one-tailed or two-tailed? What is the Critical Value?
