Apolling organization took a random sample of 3,000 middle school students to determine how many have a dog. suppose that 57% of all middle school students have a dog. if the total population of middle school students is 8 million, is the 10% condition met? justify your answer.
a. no, 0.10(8,000,000) = 800,000, which is more than the sample.
b. no, 10(8,000,000) = 80,000,000, which is more than the sample.
c. yes, 0.10(3,000) = 300 students, which is less than the total population.
d. yes, 10(3,000) = 30,000, which is less than the total population.
e. there is not enough information to determine whether the 10% condition is met.
