Question
The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.54 liters. A health campaign promotes the consumption of at least 2.0 liters per day. A sample of 10 adults after the campaign shows the following consumption in liters:
| 1.35 | 1.68 | 1.76 | 2.00 | 1.84 | 1.84 | 1.50 | 1.82 | 1.86 | 1.60 |
At the 0.050 significance level, can we conclude that water consumption has increased? Calculate and interpret the p-value.
