Quality sleep is essential for cognitive functioning and overall well-being. However, researchers still have much to learn about the specific lifestyle factors that disrupt sleep patterns across different age groups. To investigate this, a health psychologist conducted a survey using a self-report questionnaire to gather data about people's bedtime routines and nighttime disruptions. Some of the data collected is presented in the tables below.
Table 1: Responses to reading a physical book before sleeping
| Do you read a physical book before sleeping? | |
|---|---|
| 'yes' | 'no' |
| 110 | 90 |
Table 2: Responses to caffeine consumption after 6 PM by age group
| Do you drink caffeinated beverages after 6 PM? | ||
|---|---|---|
| 'yes' | 'no' | |
| Young adults (18-35) | 45 | 35 |
| Older adults (36+) | 25 | 55 |
Table 3: Primary sleep disruptors reported by participants
| Primary Sleep Disruptor | Number of people |
|---|---|
| Noise | 30 |
| Temperature | 45 |
| Stress/Anxiety | 65 |
| Screen time | 40 |
| Physical health | 20 |
Identify the appropriate inferential statistical test to use in this study to analyse the data obtained from the question asking about whether people drink caffeinated beverages after 6 PM or not. Give reasons for your answer.
