Answer:
0.28
Step-by-step explanation:
Refer the attached figure
Given :
People who live in their hometown and graduated from the college =8
People who do not live in their hometown and graduated from the college = 10
People who did not graduate from college and lives in home town = 6
People who did not graduate from college and do not live in home town = 4
To Find : Among people who do not live in their hometown, what is the relative frequency of not graduating from college?
Solution :
The total no. of people who do not live in home town whether they are graduated or not graduated = 14
People who did not graduate from college and do not live in home town = 4
Thus Among people who do not live in their hometown the relative frequency of not graduating from college :
People who did not graduate from college and do not live in home town/total no. of people who do not live in home town whether they are graduated or not graduated
⇒
⇒
⇒
Thus , Among people who do not live in their hometown the relative frequency of not graduating from college = 0.28
Answer:
- Using conditional probabilities it can be shown that the results are influenced by the gender.
Explanation:
To prove that the results are influenced by <em>gender</em> you can calculate both the probability of preferring hot dogs and the conditional probability of preferring a hot dog given that is a female.
If the two results are different the probability of preferring hot dog is dependent on whether the person is a female or a male.
The probability of preferring hot dogs given that is a female is stated by the problem: 34.2%.
The probability of preferring hot dogs by the whole sample is:
- Number of males that prefer hot dogs: 184 (stated by the problem)
- Number of females that prefer hot dogs:
100% - 34.2% = 65.8%
65.8% of 635 = 0.658 × 635 = 417.83 ≈ 418
- Samples size: 542 males + 635 females = 1177
- Probability of preferring hot dogs =
number of students that preffer hot dogs / number of students =
(184 + 418) / 1177 = 602 / 1177 = 0.5115 ≈ 51.2%
Thus, the probability of preferring hot dogs given that the student is a female (34.2%) is different from the probability of preferring hot dog for the whole sample, making the results dependent of the gender.
