Final answer:
The proportion of students who smoke is approximately 0.177 when calculated by dividing the number of students who smoke (65) by the total number of students surveyed (368), rounded to three decimal places.
Step-by-step explanation:
To find the proportion of students who smoke, you need to divide the number of students who smoke by the total number of students surveyed. In this case, there are 65 students who smoke and a total of 368 students surveyed (65 who smoke + 303 who do not).
The proportion is calculated as follows:
Proportion who smoke = Number of students who smoke / Total number of students surveyed
Proportion who smoke = 65 / 368
Proportion who smoke ≈ 0.177 (rounded to three decimal places)
