A company is conducting a survey to test the hypothesis that 75% of people have tried their product. They survey 768 random people and find that the result is not statistically significant at the .01 level. Let x be the percentage of people who said yes, they've tried the product. What is the smallest x could be? Use a normal approximation. Note: x is a percentage so it must be a number between 0 and 100, like 65.1 or 72.3282
