A laboratory claims that the mean sodium level, u, of a healthy adult is 139 mEq per liter of blood. To test this claim, a random sample of 36
adult patients is evaluated. The mean sodium level for the sample is 142 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 0.1 level of
significance, that the population mean adult sodium level differs from that claimed by the laboratory?
Perform a two-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a
list of formulas.)
