Question

find the mean, variance, and standard deviation for the data set 8 14 14 9 10
the mean is \\( \bar{x} = \square \\).

Explanation:

Step1: Identify data set

The data set is \(8, 14, 14, 9, 10\).

Step2: Calculate sum of data

Sum \(= 8 + 14 + 14 + 9 + 10 = 55\).

Step3: Calculate mean

Mean \(\bar{x}=\frac{\text{Sum}}{\text{Number of data points}}=\frac{55}{5} = 11\).

Answer:

\(11\)
