Which data set has a wider spread? Why? Set A: {9, 11, 24, 11, 4, 20, 16, 7, 18, 15, 28, 6} Set B: {9, 12, 15, 3, 21, 24, 5, 9,

Data Set A:
Lowest Value is 4
Highest Value is 28
Range = 28 - 4 = 24
Data Set B:
Lowest Value is 3
Highest Value is 24
Range = 24 - 3 = 21
Data Set A has bigger range than Data Set B, hence it has a wider range
Answer: Set A has a wider spread because its range is greater.
Hey! Apologies that I can’t make this look nice because I’m on mobile.
To simplify this, we can multiply the denominator by its conjugate. For a imaginary function (a+bi), its conjugate would be (a-bi), so we can apply that here to multiply both sides by (2-i)/(2-i). This works because it simplifies to one. Then, we have our fraction as 4*(2-i)/((2-i)(2+i))=(8-4i)/(4-i^2)=(8-4i)/5
Feel free to ask further questions, and have a great rest of your day!
