It is known that under ordinary conditions, 15% of people will not contract a certain disease. Consider the situation in which test groups of 800 were selected and the percentages of those who did not contract the disease were recorded. According to the Central Limit Theorem, percentages of groups of 800 who do not contract the disease are approximately normally distributed. Find the mean of this normal distribution. (Give your answer as a whole number.) mean: Find the standard deviation of this normal distribution. (Use decimal notation. Give your answer to one decimal place.) standard deviation: For what percentage of such groups (of 800) will 128 or fewer not contract the disease? (Use decimal notation. Give your answer to one decimal place.) percentage:
