Question

some friends played a trivia game and recorded their scores.
trivia game scores
what is the mean of the numbers?

Explanation:

Step1: Identify each score

Suzie's score: \(60\), Nora's score: \(90\), Tessa's score: \(15\), Carla's score: \(95\), Rosa's score: \(45\), Dillon's score: \(90\)

Step2: Calculate the sum of scores

\(60 + 90+15 + 95+45 + 90\)
\(= (60+90)+(15 + 95)+(45 + 90)\)
\(=150+110 + 135\)
\(=395\)

Step3: Calculate the number of data - points

There are \(n = 6\) friends (data - points)

Step4: Calculate the mean

The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\)
\(\bar{x}=\frac{395}{6}\approx65.83\)

Answer:

\(65.83\)
