neonofarm [45]

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

⇒\frac{4}{14}

⇒\frac{2}{7}

⇒0.28

Thus , Among people who do not live in their hometown the relative frequency of not graduating from college = 0.28

Brent claims that more students at his school prefer hot dogs over hamburgers. His friend Shaun doesn’t agree. To settle their a
photoshop1234 [79]

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.
