Conduct a hypothesis test to evaluate if these data provide evidence of a difference between the proportions of truck drivers and non-transportation workers (the control group) who get less than 6 hours of sleep per day, i.e. are considered sleep deprived.
The test statistic is: Z =
The P-value is

Transcribed Image Text:**Table: Sleep Duration Among Transportation Professionals**
This table presents the distribution of sleep duration among different groups, including a control group and various categories of transportation professionals: pilots, truck drivers, train operators, and bus/taxi/limo drivers.
| Sleep Duration | Control | Pilots | Truck Drivers | Train Operators | Bus/Taxi/Limo Drivers |
|-------------------------------|---------|--------|---------------|-----------------|-----------------------|
| **Less than 6 hours of sleep** | 35 | 19 | 35 | 29 | 21 |
| **6 to 8 hours of sleep** | 193 | 132 | 117 | 119 | 131 |
| **More than 8 hours** | 64 | 51 | 51 | 32 | 58 |
| **Total** | 292 | 202 | 203 | 180 | 210 |
- **Control Group**: Represents a baseline group for comparison, as seen with the highest reporting of 6 to 8 hours of sleep (193 individuals).
- **Transportation Professionals**:
- **Pilots**: Majority (132) get 6 to 8 hours of sleep, with fewer sleeping less than 6 hours (19) or more than 8 hours (51).
- **Truck Drivers**: An equal number of individuals report less than 6 hours and more than 8 hours of sleep (51 each), but most get 6 to 8 hours (117).
- **Train Operators**: Similar to truck drivers, with a majority sleeping 6 to 8 hours (119).
- **Bus/Taxi/Limo Drivers**: Show a distribution with the majority getting 6 to 8 hours of sleep (131), and the least number getting less than 6 hours (21).
This data provides insight into sleep patterns across different transportation sectors, highlighting variations in sleep duration preferences and potential areas for sleep-related interventions.
