Transcribed Image Text:Q4. Suppose a poll of 15 voters is taken in a large city. The purpose is to determine x, the
number who favor a certain candidate for mayor. Suppose that 60% of all the city's voters
favor the candidate.
a. Find the mean and standard deviation of x.
b. What is the probability that x <=10.
c. Find the probability that x> 12.
d. 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?
