Answer 1

Tina collected data from a random sample of 600 students in her university asking whether or not they exercise more than 30 minutes per day. Based on the results, she reports that 53% of the students in the nation exercise more than 30 minutes per day. Why is this statistic misleading?

This statistic is misleading because Tina collected a university data and then made her conclusion based on a wrong population sample, that is, the nation.

Step-by-step explanation:

Based on the information given in the question, it is observed that her sample population was 600 university students, but the report of her study indicates vividly that she made her conclusion based on a wrong population sample, that is, the nation.

Therefore, the sample is biased, and the result obtained by her is misleading.

Answer 2

The sample is biased.

Step-by-step explanation:

In this case the sample is biased. The individuals included in the survey are not representative of the general population, as their school students do not generally have the same workout patterns as the entire population of national students.
