The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.56 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:

1.88 1.74 1.98 1.70 1.86 1.72 1.74 1.98 1.68 1.50

At the 0.025 significance level, can we conclude that water consumption has increased? Calculate and interpret the p-value
