The proportion is the number of students in total/the amount of students who voted lasagna, you add all the votes together to get how many students there are in total (10+6+4=20) and 6 students voted for lasagna so the proportion would be 6/20 then you simplify it to 3/10 so the proportion of the students who like lasagna as their favorite pasta dish is 3/10

Answer:

The interval is for those that want to get out earlier is between 43 student to 47 students

The interval is for those that want to get out later is between 48 student to 50 students

Step-by-step explanation:

Given that:

sample size n=128

Probability of those that want to get out earlier = 0.35.

The mean = n × probability = 0.35 × 128 = 44.8 ≈ 45

Margin of error = 4% = 0.04 × 44.8 = 1.79 ≈ 2

Therefore the interval = mean ± Margin of error = 45 ± 2 = (43, 47)

The interval is for those that want to get out earlier is between 43 student to 47 students

Probability of those that want to get out later = 0.39.

The mean = n × probability = 0.39 × 128 = 49.92 ≈ 50

Margin of error = 4% = 0.04 × 50 = 2

Therefore the interval = mean ± Margin of error = 50 ± 2 = (48, 52)

The interval is for those that want to get out later is between 48 student to 50 students

the group that wants to get out of school earlier to win after all the votes are counted if those that have no opinion decide that they want to go earlier
