Answer:
The given data is not normal.
Step-by-step explanation:
We are given the following data:
30, 59, 69, 50, 58, 71, 55, 43, 3, 66, 52, 56, 62, 36, 13, 29, 17, 31
Condition for normality:
Mean = Mode = Median
Mode is the most frequent observation of the data.
Since all the value appeared once, there is no mode.
Sorted data: 3, 13, 17, 29, 30, 31, 36, 43, 50, 52, 55, 56, 58, 59, 62, 66, 69, 71
Median =
Since the mean, mode and median of data are not equal, the data is not normal.
