Answer 1

B. 6/19. The sample proportion of students who took fewer than the mean number of electives is 6/19.

Step-by-step explanation:

To find the sample proportion of students who took fewer than the mean number of electives, we need to count the number of students in the sample who took fewer than 7.63 electives. Out of the 19 students in the sample, 6 students took fewer electives than the mean. Therefore, the sample proportion is 6/19.
