Question

Sample: 17,13,6,8,21 The arithmetic mean of a variable is computed number of observations. The population arithm arithmetic mean, bar (x), is computed using sample compute the mean for this data set.

Answer 1

To calculate the arithmetic mean (average) of the given data set: 17, 13, 6, 8, and 21, you need to sum up all the values and then divide by the number of observations.

1. Sum up all the values:

17 + 13 + 6 + 8 + 21 = 65

2. Count the number of observations, which in this case is 5.

3. Calculate the arithmetic mean:

Mean (x) = Sum of values / Number of observations

Mean (x) = 65 / 5

Mean (x) = 13

So, the arithmetic mean of the given data set is 13.
