Question

the graph shows the relationship between daily caffeine consumption and resting heart rate for some adults. which phrases describe the relationship between heart rate and daily intake of caffeine? select two options. negative correlation increasing heart rate constant correlation positive correlation decreasing heart rate

Explanation:

• A positive correlation means that as one variable (caffeine intake) increases, the other variable (heart rate) also tends to increase. Looking at the scatter - plot, as the number of coffee cups (caffeine intake) increases, the resting heart rate generally shows an upward trend.
• The overall pattern of the data points in the scatter - plot indicates that with more caffeine consumption (more cups of coffee), the resting heart rate is higher. So, it is an increasing heart rate in the context of higher caffeine intake.

Answer:

increasing heart rate, positive correlation
