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 liter


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.

a. State the null hypothesis and the alternate hypothesis. (Round your answers to 2 decimal places.)

b. State the decision rule for 0.01 significance level. (Round your answer to 3 decimal places.)

c. Compute the value of the test statistic. (Round your intermediate and final answer to 3 decimal places.)

d. At the 0.01 level, can we conclude that water consumption has increased?

A laboratory claims that the mean sodium level, w, of a healthy adult is 139 meg per liter of blood. To test this claim, a random sample of 24 adult patients is evaluated. The mean sodium level for the sample is 134 mEq per liter of blood. It is known that the population standard deviation of adult sodium levels is 13 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.01 level of significance, that the...
