The International Surfing Association (ISA) is interested in determining the number of potential locations for competitions. They have requirements of at least 25 "surfable" waves per hour during peak surf hours. To find acceptable locations, they had members all over the world submit data from their local beach. The locations had a mean of 32 waves per hour and a standard deviation of 4 waves per hour. what percentage of beaches meet the requirement to be selected by the ISA? (Hint: Use the tables in the Chapter Modules) 1.75 -1.75 0.0401 0.9599 0.7881
