The scientists are trying to find if TV causes aggressions. TV is the independent variable and aggression depends on if the adults watch the TV.
Answer:
0.08
Explanation:
"p" bar is the fraction defective.
"sp" is the standard deviation.
"n" is the sample size.
"z" is the number of standard deviations for a specific confidence.
And z = 3 (99.7 percent confidence) or
z = 2.58 (99 percent confidence) is used.
In this problem, p bar is 0.05 and sp= 0.01
thus, 0.05 + (3 x 0.01) = 0.08
The resulting UCL value for the line is 0.08.
Answer:
Complex
Explanation:
An organizational structure can be defined as the process which typically involves dividing an organization into various functional units.
A matrix organizational structure is a type work structure where reporting relationships between employees are set up as a matrix rather than the conventional hierarchy approach.
This ultimately implies that, there are two (2) chains of command; employees have dual reporting relationships to both a project and functional manager.
Basically, the matrix organizational structure can be classified into three (3) categories, these are;
1. Weak matrix structure.
2. Balanced matrix structure.
3. Strong matrix structure.
One of the frequent complaint about a matrix organizational structure is that the exchange or dissemination of informations (communications) are complex because there exist a dual reporting relationships.
Answer:
a) i) 13.5% ii) risk on portfolio = 13.63%
b) Volatility of the portfolio (13.65%) is < Volatilities of the individual indexes
Explanation:
<u>A) Determine the return and risk of the portfolio</u>
i) Return [ E(r^p) ] = ∑ wi*ri ---- ( 1 )
where : wi = weight of stocks , ri = rate of return ( estimated ) N = number of stocks
Back to equation 1
E(r^p) = (0.5*14% ) + (0.5*13% ) = 13.5%
<em>ii) risk of portfolio </em>
we can determine the risk of portfolio using the equation below
Vol [ r( t + 1 , $ ) + s ( t + 1 ) ] ( volatility on Japanese equity ) = 13.63%
attached below is the remaining solution
<u>b) comparing the Volatilities </u>
Volatility of the portfolio (13.65%) is < Volatilities of the individual indexes ( i.e. volatility of US return ( 15.5% ) , Volatility of EAFE return ( 16.5% ) )
Answer:
The correct word for the blank space is: states.
Explanation:
Italian economist Vilfredo Pareto (<em>1848-1923</em>) proposed the 80/20 rule in which he explains 80% of the effects of anything are the result of 20% of the causes of something. When applied to the sales world, it implies 80% of an individual sales come from only 20% of the individual's customers.
