The PMBOK suggests that project managers spend 75-90 percent of their time communicating. In my personal experience it is much closer to 90 percent.
90 percent
Elton Mayo (1880-1949), best known for his Hawthorne experiments, introduced rest pauses in industrial plants and in so doing reduced employee turnover from 250 percent to 5 percent in some cases.
The independent variable explains .32*100 percent of the variance in the dependent variable.This is 9%.The explainable variance is always the square of the correlation (r).
If the budgeted amount is 0 and the actual amount is $300, what is the variance percentage?
r2, the coefficient of determination
100%
14.7 is 35 percent of 42.
40% of 78 is 31.2

223 x 56.6% = 126.22
If you assume a binomial distribution, the variance is n*p*(1-p) where n is the number of voters = 30 p is the probability of support = 0.36 So variance = 30*0.36*0.64 = 6.912
93%.
actual answer= 293.8 estimated answer= 294.0
