Question

students from four different towns were surveyed about whether they prefer indoor or outdoor sports. the results are shown in the table:

	town a	town b	town c	town d	total
outdoor sports	20	25	40	35	120
total	45	55	80	50	230

answer options to the blanks to justify a positive association between preferring outdoor sports and living in town d:

there is a positive association because the ____________ who prefer __________ sports is greater than the __________ who prefer ____________ sports

• number of students from town d
• percentage of students from town d
• total number of students
• percentage of all students
• indoor
• outdoor

Explanation:

Step1: Calculate percentage for outdoor in Town D

First, find the percentage of students from Town D who prefer outdoor sports. The number of outdoor - preferring students in Town D is 35, and the total number of students in Town D is 50. So the percentage is $\frac{35}{50}\times100\% = 70\%$.

Step2: Calculate percentage for indoor in Town D

Next, find the percentage of students from Town D who prefer indoor sports. The number of indoor - preferring students in Town D is 15, and the total number of students in Town D is 50. So the percentage is $\frac{15}{50}\times100\%=30\%$.

Step3: Compare the two percentages

We compare the percentage of students from Town D who prefer outdoor sports (70%) with the percentage of students from Town D who prefer indoor sports (30%). Since 70% > 30%, there is a positive association because the percentage of students from Town D who prefer outdoor sports is greater than the percentage of students from Town D who prefer indoor sports.

Answer:

percentage of students from Town D; outdoor; percentage of students from Town D; indoor
