Answer:
Average attendance with outlier = 39
Average attendance without outlier = 35.3
Step-by-step explanation:
Given the following data 34, 37, 30, 65, 34, 38, 41, 33
The outlier is the value that is lower or higher than other values in the dataset. Hence the outlier in this case is 65
Average = Sum of data/sample size
With the outlier;
Sum of dataset = 34+37+30+65+34+38+41+33
Sum of datasets = 312
Sample size = 8
Average attendance with the outlier = 312/8
Average attendance with the outlier = 39
Without the outlier;
The required data will exclude 65;
34, 37, 30, 34, 38, 41, 33
Sum of data = 34+37+30+34+38+41+33
Sum of data = 247
Sample size = 7
Average attendance without outlier = 247/7
Average attendance without outlier = 35.3
