Chapter 02, Testbank, Question 067-072

The following table gives the cumulative frequency distribution of the commuting time (in minutes) from home to work for a sample of 400 persons selected from a city.

Time (minutes)	f
0 to less than 10	64
0 to less than 20	157
0 to less than 30	222
0 to less than 40	288
0 to less than 50	352
0 to less than 60	400

The sample size is:

The percentage of persons who commute for less than 30 minutes, rounded to two decimal places, is:

The cumulative relative frequency of the fourth class, rounded to four decimal places, is:

The percentage of persons who commute for 40 or more minutes, rounded to two decimal places, is:

The percentage of persons who commute for less than 50 minutes, rounded to two decimal places, is:

The number of persons who commute for 20 or more minutes is:

Chapter 03, Testbank, Question 027-029

Chapter 04, Testbank, Question 021-026

The following table gives the two-way classification of 500 students based on sex and whether or not they suffer from math anxiety.

Suffer From Math Anxiety

Sex	Yes	No
Male	200	40
Female	135	125

If you randomly select one student from these 500 students, the probability that this selected student is a female is: (round your answer to three decimal places, so 0.0857 would be 0.086)

If you randomly select one student from these 500 students, the probability that this selected student suffers from math anxiety is: (round your answer to three decimal places, so 0.0857 would be 0.086)

If you randomly select one student from these 500 students, the probability that this selected student suffers from math anxiety, given that he is a male is: (round your answer to three decimal places, so 0.0857 would be 0.086)

If you randomly select one student from these 500 students, the probability that this selected student is a female, given that she does not suffer from math anxiety is: (round your answer to three decimal places, so 0.0857 would be 0.086)

Which of the following pairs of events are mutually exclusive?

Male and yes

Female and no

No and yes

Female and yes

Female and male

Male and no

Are the events "Has math anxiety" and "Person is female" independent or dependent? Detail the calculations you performed to determine this.
