Answer:
A.
mean = 724.2
Median = 715
Mode = 768
B.
Range = 85
Standard deviation = 29.30
C.
Interval = [665.6, 782.8]
Step-by-step explanation:
Number of samples n = 25
Summation X= 769 + 691 + 699 +730+711+ 765+ 702 718 +719 +712+ 768 +688 +757+695 768 +735 +709 +758 +708+ 693 +736 700+ 687 +772 +715 = 18105
A.
1. Mean = 18105/25
= 724.2
2. Median is the middle value when arranged from the least value to the highest = 715
3. Mode is the number with the highest frequency = 768 (occured two times)
B.
1. Range = highest value - lowest value
Highest value = 772
Lowest value = 687
772-687 = 85
2. Standard deviation = √(X-barX)²/n-1
= √20604/25-1
=√858.5
= 29.30
Please check attachment for the full calculation of the standard deviation
C.
Interval
[Mean - 2(sd), mean + 2(sd)]
= [724.2-2x29.3, 724.2+2x29.3]
=[665.6, 782.8]
Answer:
Nominal Interest rate=11.9%
Step-by-step explanations:
The Fisher effect is a theory propounded by an economist named Irving Fisher.
Fisher's equation shows the relationship between real Interest rate, expected inflation rate and nominal Interest rate.
It can be calculated by subtracting the expected inflation rate from the nominal Interest rate to give the real Interest rate.
Real Interest rate= nominal Interest rate - expected inflation rate
Given,
Real Interest rate= 4.4%=0.044
Expected inflation rate=7.5%=0.075
Nominal Interest rate=?
Therefore,
Real Interest rate=nominal Interest rate - expected inflation rate
Nominal Interest rate=Real Interest rate+expected inflation rate
Nominal Interest rate=0.044+0.075
Nominal Interest rate=0.119
Nominal Interest rate=11.9%
The square root of 81 is 9
X should be 7 after doing all the calculation.
"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."
