Multiple Choice

Provide an appropriate response.
-The amount of money, in dollars, that an employee of a bank spent on lunch on six randomly selected days yielded the following data set: $8,9,6,18,11,18$
Compute $\left( \sum x _ { i } \right) ^ { 2 }$ and $\sum x _ { i } ^ { 2 }$ . Explain the difference between the two quantities.

• A)70 and \(4900 ; \left( \sum x _ { i } \right) ^ { 2 }\) is the sum of the squares of the data, whereas \(\sum x _ { i } ^ { 2 }\) represents the square of the sum of the data.
• B) 950 and \(4900 ; \left( \sum \mathrm { x } _ { \mathrm { i } } \right) ^ { 2 }\) is the sum of the squares of the data, whereas \(\sum \mathrm { x } _ { \mathrm { i } } ^ { 2 }\) represents the square of the sum of the data.
• C) 4761 and \(70 ; \left( \sum x _ { i } \right) ^ { 2 }\) is the square of the sum of the data, whereas \(\sum x _ { i } ^ { 2 }\) represents the sum of the squares of the data.
• D) 4900 and \(950 ; \left( \sum \mathrm { x } _ { \mathrm { i } } \right) ^ { 2 }\) is the square of the sum of the data, whereas \(\sum \mathrm { x } ^ { 2 }\) represents the sum of \(^ { 2 }\) the squares of the data.
