researcher wants to determine if the statement made in the advertisement is false. She randomly test drives 38 small cars at 75 miles per hour and records the braking distance. The sample average braking distance is computed as 116 feet. Assume that the population standard deviation is 23 feet. (You may find it useful to reference the appropriate table: 2 table or t table) 7 It is advertised that the average braking distance for a small car traveling at 75 miles per hour equals 120 feet.
