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

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.

Adjust the compass to width AC/AB and with the compass at B/C, mark an arc across the circle to be the next vertex of the hexagon.

Step-by-step explanation:

The steps in constructing a regular hexagon inscribed in a circle are:

  • Marking a point on the circle to be the first vertex of the hexagon
  • Place compass on the point and adjust it to the center of the circle
  • Mark an arc across the circle to be the next vertex of the hexagon
  • Move the compass to this new vertex and mark another arc for the next vertex of the hexagon
  • Repeat this step to achieve all 6 vertices
  • Using a straight edge draw a line between each point and the next one on the circle
  • The result is an inscribed hexagon in a circle
