Question

the counselor picked a random sample of 160 senior scores and recorded the information in the table below. use this data to answer questions 1 - 5. students that scored less than 20.8 104 students that scored 20.8 and higher. 56 1. what is the proportion of students that scored less than 20.8 on the act at lincoln high school?

Explanation:

Step1: Recall the formula for proportion

Proportion \(p=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\)

Step2: Identify the values from the table

The number of students who scored less than \(20.8\) is \(104\), and the total number of students in the sample is \(104 + 56=160\)

Step3: Calculate the proportion

\(p=\frac{104}{160}\)
Simplify the fraction: \(\frac{104\div 16}{160\div 16}=\frac{6.5}{10}=0.65\)

Answer:

\(0.65\)
