Question
1. In a set of scores, u = 300 and a = 65,5, Find the scores one, two, and three standard deviations above the mean and the scores one, two, and three standard deviations below the mean. 2. In a particular normally distributed set of scores, the mean is 65.75 and thestandard deviation is 25.68. Determine the approximate location of the score x = 73.52 in terms of the standard deviation. 3. Determine the probability density function of the standard normal distribution. 4. Vienna is testing the effect of Povidone iodine as antisepticmedicine in treating minor wounds. Minor wounds heal at an average rate ofµ = 6.7 days with a standard deviation of a = 0.8 day. After using the medicine, the wound healed after 4 days. How far in terms of the standard deviation from the mean is the healing rate of the wounds using Povidone iodine? Assume that the healing rates of wounds are normally distributed. %3D
