Question

Each year, the high school guidance counselors conduct a survey to estimate the proportion of students at the school who cheat on their homework. Based on a random sample of 300 students from the high school, a 99% confidence interval for the proportion of all students at the high school who cheat on their homework is 0.052 to 0.192. Describe how untruthful answers might lead to bias in this survey. Does the stated margin of error account for this possible bias

Answer 1

The stated margin of error would account for the possible bias caused by wrong answers due to the closeness of the confidence interval

Explanation:

Random sample = 300

99% confidence interval of student who cheat : 0.052 to 0.192

The confidence interval is too close that it only contains the population parameter, this means that almost every subject in the Given population will have to be measured.

Since This is an impractical approach it will lead to untruthful answers been produced which will cause bias. hence the stated margin of error would account for the possible bias caused by wrong answers.
