Final answer:
c, average daily temperature and number of people at the beach, illustrates a positive correlation where one variable increases as the other also increases.
Step-by-step explanation:
The correct answer is option c. This option states that there is a positive correlation between average daily temperature and the number of people at the beach. As the temperature increases, more people are likely to go to the beach to enjoy the sun and swim.
This is a classic example of a positive correlation where the rise in one variable tends to be associated with a rise in the other.
Option a would more likely represent a negative correlation, as increased time playing computer games is typically associated with less time spent outdoors.
Option b might also be considered a negative correlation, since missing more days from work could lead to lower production bonus wages.
Option d does not necessarily represent a positive or negative correlation, as having more students in a class does not ensure that the time spent with each student will increase or decrease.
Understanding the difference between positive correlation and negative correlation is important for analyzing data and recognizing patterns within various fields such as statistics, mathematics, and social sciences.
