Find the probability that x = 11 e. Graph the probability distribution of x. Q5. A study explaining the relationship between knowledge management and human capital development has been reported in Business Performance Management Journal (Vol. 16, 2010) among 401 employees and has also found that employees' age is positively related to involvement in tactical knowledge management. Assume that employees' age follow normal distribution with mean age of 36.71 years and standard deviation of 11.92 years. An employee is randomly selected from this study, and let x equal the age of the randomly selected employee. 1. What is the probability that x less than 36.71 years and more than 36.71 years? 2. What is the probability that x falls between 30 and 40 years? 3. What is the probability that x greater than 39 years? 4. What is the probability that x less than 35 years?
