The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.46 liters. A sample of 10 adults after the campaign shows the following consumption in liters. A health campaign promotes the consumption of at least 2.0 liters per day: 
1.78 1.90 1.38 1.60 1.80 1.30 1.56 1.90 1.90 1.68 
At the 0.050 significance level, can we conclude that water consumption has increased? Calculate and interpret the pvalue. 
a.  State the null hypothesis and the alternate hypothesis. (Round your answers to 2 decimal places.) 
H_{0}: μ ≤  
H_{1}: μ >  
b.  State the decision rule for 0.050 significance level. (Round your answer to 3 decimal places.) 
Reject H_{0} if t> 
c. 
Compute the value of the test statistic. (Round your intermediate and final answer to 3 decimal places.) 
Value of the test statistic 
d.  At the 0.050 level, can we conclude that water consumption has increased?
