6. The strength of glasses for myopia uis usually given in diopters. A diopter is the reciprocal of the focal length in meters. So -2 diopter glasses have focal length 1/(-2)m = .5m. Why is the dopter negative for myopia? Is a -3 diopter prescription stronger or weaker than s -2 dopter prescription?

3. According to statistical theory, if any measurement of a given quantity has a deviation greater than 3e, a from the mean of that quantity, it is very unlikely that it is statistical variation, but rather is more likely to be a mistake. Cakulate the value of 3al Do any of your measurements of length have a deviation from the mean greater than that value? If so, calculate how many times larger than f De...
