Surveys of students' parents born in michigan. are the students independent or not.

a. No, they are not independent

Step-by-step explanation:

The probability that a student's father was born in Michigan is:

48 / 100 = 48%

For students' whose mother was born in Michigan, the probability that their father was also born in Michigan is:

29 / 73 = 40%

Since these probabilities are not the same, the events are not independent.  The probability of one event is affected by the occurrence of the other event.
