Answer #1

Proportion of patients needing emergency service wait 9 minutes or less =

= Number of patients needing emergency service wait 9 minutes or less / Total number of patients

We have,

Total number of patients = 20

The data is :

2
5
10
12
4
4
5
17
11
8
9
8
12
21
6
8
7
13
18
3

Number of patients needing emergency service wait 9 minutes or less = 12

Proportion of patients needing emergency service wait 9 minutes or less = 12 / 20 = 0.60 = 60%
