D) 50

b) Use the completed table from Part a. What percentage of the people surveyed were teachers?
A) 40%
B) 30%
C) 60%
D) 20%

Answer 1

The completed frequency table should show that 30 students and 20 teachers voted 'yes' for a later start. To find the percentage of teachers in the survey, calculate 30 teachers divided by 75 total people, multiplied by 100, yielding 40%.

Step-by-step explanation:

To answer the question about completing the frequency table and determining the percentage of teachers in the survey:

1. Frequency Table: Out of the 75 people surveyed, we know that 45 were students. Therefore, the rest were teachers which gives us 75 - 45 = 30 teachers. We also know that 50 people in total voted 'yes' for the later start, and out of those, 30 were students. Thus, the number of teachers who voted 'yes' can be found by subtracting the number of students who voted 'yes' from the total number of 'yes' votes, which is 50 - 30 = 20.
   The completed frequency table would show 30 students voted 'yes' and 20 teachers voted 'yes' for a later start.
2. Percentage of Teachers: To find the percentage of the people surveyed who were teachers, we divide the number of teachers by the total number of people surveyed and then multiply by 100: (30 teachers / 75 total people) * 100 = 40%. Therefore, the percentage of the people surveyed who were teachers is 40%.
