Answer 1

Chart relating to the question is attached below.

Answer:

349 students

Explanation:

Based on the chart given, we can obtain the experimental probability or proportion for the travel plan of 75 students :

Proportion who would be traveling by car :

Number traveling By car / number of samples

p(car) = 23 / 75 = 0.30666

If total number of students = 1138

Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :

= 0.30666 * 1138

= 348.98 students

= 349 students
