A population of measurements is approximately normally distributed with mean of 25 and a variance of 9. Find the probability that a measurement selected at random will be between 19 and 31. Solution: The values 19 and 31 must be transformed into the corresponding z values and then the area between the two z values found. Using the transformation formula from X to z (where µ = 25 and σ √9 = 3)‚ we have z19 = (19 – 25) / 3 = -2 and z31 = (31 - 25) / 3 = +2 From the area between z =±2 is 2(0

As I mature‚ I begin to fathom and realize that we are continually waging war against time. Time. All of us‚ in at least one trice in our life‚ wanted to sojourn or hasten time. We wanted to live one moment forever. And sometimes‚ we want to expunge an instance in our lives that we revile and berate. But life is not a DVD which we could pause or fast forward with just a single click of a remote. After all is said and done‚ we could still say that time has won in this hostility. Sometimes

Then silence. I am the biggest apple of my parents’ eyes‚ given the fact that I am the only child in the family. It is therefore not surprising to see them buying whatever I want‚ and getting the latest gadget seemed pedestrian. Household chores are neither a necessity
