Jan Smith, age 59, presents to the clinic with complaints or pain and numbness of her right leg while ambulating. The pain radiates toward her hip and down the back of her leg and goes away with rest. She reports having these symptoms for at least six months, but now it seems as though she is able to walk less and less before the pain sets in. She endorses a sedentary lifestyle and she smokes a pack and a half...

3. Sampling Distribution: Suppose you collect a random sample of 100 students from a population and estimate that ?̅=67 inches and s=6. a) What is your “best-guess” estimate of the population mean (µ)? b) How likely is it that your “best-guess” estimate lies within 1 inch of the true mean (µ)? How do I do this problem

a. Compare 3 estimating techniques: Analogous, Bottom-up and Parametric. Explain the circumstances which determine the method you should use each type as your primary method b. According to PMI (2017, p. 245) There are two common ways to estimate cost and duration using the 3-poin average of the optimistic (O), most likely (M), and pessimistic (P) estim estimate (0+M+P)/3. The second way is based on the Beta distribution that puts more weight on the most likely. Mathematically, your beta estimate...
