1. Most projects completed using traditional project management are done in a weak matrix organization. Most projects completed in an agile project management framework use a strong matrix or pure project environment. Why is this so? Solution Traditional project management involves defined planning and disciplined approach. The idea is that all stages or project are clearly recognisable and the sequence is defined. Weak matrix organisation is used in traditional project management because:- Agile management system is dynamic management with information led decisions and solutions, ability to respond to opportunities and risks. Influencing and shaping environment along with early identification of emerging trends are characteristics of this management Strong matrix organisation is used in agile project management because:-.

1. 1. Mrs. Benton’s class had an average of 85 on the TLI math test. The standard deviation for the
class is 10.06. If the girl’s scores are 100, 65, 67, 72, 80, 85, 85, 73 and using a level of
significance of .05, what should we conclude?
The girl’s average is not significantly different from the class.
The girl’s average is significantly different from the class.
Girls did significantly better than the boys.
Boys did significantly better than the girls.
Solution
Given n=8, xbar=78.375, s= 11.56 (based on the data)
The test hypothesis is
Ho:=85
Ha: not equal to 85
The test statistic is
t=(xbar-)/(s/n)
=(78.375-85)/(11.56/sqrt(8))
=-1.62
Given a=0.05, the critical value is t(0.025, df=n-1=7)=-2.36 (check student t table)
Since t=-1.62 is larger than -2.36, we do not reject Ho.
Answer: The girl’s average is not significantly different from the class.
