A leading medical journal claims that 68% of high school students experience anxiety just before an exam. A school counselor wants to conduct a survey to verify this with the students in her school and wants to do so with a margin of error (ME) of ±7%. What minimum sample size, rounded to the nearest whole person, does the counselor need to use?

Hint: , where is the yes proportion in the sample and N is the sample size.

N ≥ 175

N ≥ 178

N ≥ 200

N ≥ 262
