Question

1. what is the mean of the data set? (round to one decimal place) using the data set of numbers from the numbers below: 17, 11, 18, 14, 12, 2, 8, 12, 16, 1, 9, 4. use this list and answers to the questions. 11

Explanation:

Step1: Find the sum of data

Sum the numbers: \(7 + 8+18 + 21+2 + 8+11 + 4+10 + 6+3+12+8+6+1+9+4+12+14+2+11+15+11+8+12 = 224\)

Step2: Calculate the number of data points

Count the numbers, there are \(n = 25\) data - points.

Step3: Calculate the mean

The mean \(\bar{x}=\frac{\text{Sum of data}}{\text{Number of data points}}=\frac{224}{25}=8.96\)

Step4: Round to one decimal place

Rounding \(8.96\) to one decimal place gives \(9.0\)

Answer:

\(9.0\)
