The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.22 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:
1.44 1.80 1.20 1.32 1.44 1.32 1.90 1.64 1.32 1.60
at the 0.050 significance level, can we conclude that water consumption has increased? calculate and interpret the p-value.
a. state the null hypothesis and the alternate hypothesis. (round your answers to 2 decimal places.)
h0: μ ≤
h1: μ >
b. state the decision rule for 0.050 significance level. (round your answer to 3 decimal places.)
reject h0 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?
h0 and conclude that water consumption has
.
e. estimate the p-value.
p-value is
