<u>Solution and Explanation:</u>
a) 51% of users of mobile phones use their phone at least once per hour,
It is a binomial distribution with n = 150, p = 0.51
mean = np = 150 multiply with 0.51 = 76.5
SD= sqrt(np(1-p) )= 6.1225
Since np and n(1-p) > 5, we can assume the distribution is normal.
B) please see the attached file.
c) It is a binomial distribution with n = 150, p = 0.02
mean = np = 150*0.02 = 3
SD= sqrt(np(1-p) )= 1.71464
Since np < 5, we cannot assume the distribution is normal.

Explanation:
Answer:
The risk premium is 4.4%
Explanation:
The risk premium on any given investment is the difference between the risky investment and the risk free investment and in this case we know treasury bonds are risk free and offer a certain return of coupons because they come from governments rather than the fictional ones like the one from risky investment inc so to find the risk premium we say :
Risk Premium = Risky investment rate - Risk free investment Rate
= 7.3% - 2.9%
= 4.4%
Answer:
D) Project importance is enhanced by setting authority equal to that of functional departments.
Explanation:
A matrix organization is characterized by, multiple command system and overlapping of command, control and behavioral pattern.
Here, temporary project groups are created so as to handle short term projects. Personnel are drawn from functional department and their activities are controlled and coordinated by a project manager.
Once a project is completed, the structure is disbanded and the personnel return to their original departments i.e functional department.
During the project duration, a person is responsible and reports to two bosses, one being the project manager and secondly to the functional boss. Thus, under such a structure exists dual reporting.
Under matrix structure for project management, the project manager is not allowed to use resources exclusively for the project i.e like in project management. Rather, such a manager is required to share resources with the organization.
