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 t after the campaign shows the following consumption in liters: 1.35 1.68 HO: US H1:p> 1.76 2.00 Reject H0 if t> 1.84 1.84 1.50 1.82 At the 0.050 significance level, can we conclude that water consumption has increased? Calculate and interpret the p-value. Click here for the Excel Data File a. State the null hypothesis and the alternate hypothesis. (Round your answers to 2 decimal places.) 1.86 b. State the decision rule for 0.050 significance level. (Round your answer to 3 decimal places.) do that water consumption has 1.60 d. At the 0.050 level, can we conclude that water consumption has increased? c. Compute the value of the test statistic. (Round your intermediate and final answer to 3 decimal places.) Value of the test statistic
