Answer:
0.157 is the proportion of students who smoke.
Step-by-step explanation:
We are given the following in the question:
Number of students who smoke = 58
Number of students who don't smoke = 311
Total number of students surveyed =
Number of students who smoke + Number of students who don't smoke
[tex]= 58 + 311\\=369[/tex]
Proportion of students who smoke =
[tex]=\displaystyle\frac{\text{Number of students who smoke}}{\text{Total number of students}}\\\\= \frac{58}{369}\\\\= 0.157[/tex]
Thus, 0.157 is the proportion of students who smoke.
