find the mean of the number of newspapers that were delivered across 5 hours. number of newspapers delivered 19, 14, 19, 21, 17 mean = ?
Answer
Explanation:
Step1: Calculate the sum of the data
$$19 + 14+19 + 21+17$$ $$=(19+19)+(14 + 17)+21$$ $$=38+31 + 21$$ $$=69+21$$ $$=90$$
Step2: Divide the sum by the number of data points
The number of data points (n = 5). The mean formula is (\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}), so (\bar{x}=\frac{90}{5})
