Question

4 keisha surveys a random sample of students at her school about whether they wear glasses. in her sample, 28 students wear glasses. the other 52 students in her sample do not. there are 506 students in keisha’s school. what inference can keisha make about the number of students in her school who wear glasses?

Explanation:

Step1: Calculate sample size

$28 + 52 = 80$

Step2: Find sample proportion of glasses wearers

$\frac{28}{80} = 0.35$

Step3: Apply proportion to school population

$0.35 \times 506 = 177.1 \approx 177$

Answer:

Approximately 177 students in the school wear glasses.
