The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.4 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: 1.5, 1.6,
1.5, 1.4, 1.9, 1.4, 1.3, 1.9, 1.8, 1.7.

At the 0.01 significance level, can we conclude* that water consumption has increased?

Calculate and interpret* the p value.
