PORTFOLIO QUESTIONS1
Exercises:
1.
Given, α = 10 for the assignment.
The three integers are a, b and c, where, a < b < c
Median is the middle most value in order and given median = 10.
Hence, b = 10.
Now, mean = α – 2 = (a + b + c)/3 = 10-2 = 8.
Range = c – a = 2*10 = 20 => c = 20+ a
Hence, (a + 10 + c)/3 = 8 => a+c+10 = 24
 a+c = 14
 a + 20 + a = 14
 2a = -6
 a = -3
Hence, c = 20 -3 = 17.
Thus the numbers are a = -3, b = 10 and c = 17.
2.
The sample data of four shops are imported to excel with α = 10.
