Question

find the mean of the data set shown in the table below. data set c: 1.74, 1.71, 1.07, 0.8, 1.13

Explanation:

Step1: Sum the data values

The data values are \(1.74\), \(1.71\), \(1.07\), \(0.8\), and \(1.13\).
Sum \(= 1.74 + 1.71 + 1.07 + 0.8 + 1.13\)
\(= (1.74 + 1.71) + (1.07 + 0.8) + 1.13\)
\(= 3.45 + 1.87 + 1.13\)
\(= 3.45 + (1.87 + 1.13)\)
\(= 3.45 + 3.0\)
\(= 6.45\)

Step2: Calculate the mean

The mean is the sum divided by the number of data points (\(n = 5\)).
Mean \(= \frac{6.45}{5}\)
\(= 1.29\)

Answer:

1.29
