Kindly check explanation
Step-by-step explanation:
Given the data :
Technician __Shutdown
Taylor, T___4
Rousche, R _ 3
Hurley, H__ 3
Huang, Hu___2
Gupta, ___ 5
The Numbe of samples of 2 possible from the 5 technicians :
We use combination :
nCr = n! ÷ (n-r)!r!
5C2 = 5!(3!)2!
5C2 = (5*4)/2 = 10
POSSIBLE COMBINATIONS :
TR, TH, THu, TG, RH, RHu, RG , HHu, HG, HuG
Sample means :
TR = (4+3)/2 = 3.5
TH = (4+3)/2 = 3.5
THu = (4+2) = 6/2 = 3
TG = (4 + 5) = 9/2 = 4.5
RH = (3+3) = 6/2 = 3
RHu = (3+2) /2 = 2.5
RG = (3 + 5) = 8/2 = 4
HHu = (3+2) = 2.5
HG = (3+5) = 8/2 = 4
HuG = (2+5) / 2 = 3.5
Mean of sample mean (3.5+3.5+3+4.5+3+2.5+4+2.5+4+3.5) / 10 = 3.4
Population mean :
(4 + 3 + 3 + 2 + 5) / 5 = 17 /5 = 3.4
Population Mean and mean of sample means are the same.
This distribution should be approximately normal.
The interest is $175
The formula we'll use for this is the simple interest formula, or: I=P*R*t
Where:
<span><span>P is the principal amount, $5000.00.
</span><span>r is the interest rate, 7% per year, or in decimal form, 7/100=0.07.
</span><span>t is the time involved, 6....month(s) time periods.
</span><span>Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into"year" as well.
Do this by dividing your time, 6- month(s), by 12, since there's 12 months in 1 year. </span><span>So, t is 0.5....year time periods.
</span></span>
To find the simple interest, we multiply 5000 × 0.07 × 0.5 to get that: $175
