friday | 16

16
17
20
29

Explanation:

Step1: Sum up the deliveries

$$13 + 15+17 + 19+16$$
$$=(13 + 17)+(15 + 19)+16$$
$$=30+34 + 16$$
$$=30+(34 + 16)$$
$$=30 + 50$$
$$=80$$

Step2: Calculate the mean

The number of days is \(n = 5\). The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{80}{5}=16\)

Answer:

16
