A medical researcher believes that, because of modern dietary habits, the mean sodium level for healthy adults, , now differs from that given in the textbook. A random sample of 16 healthy adults is evaluated. The mean sodium level for the sample is 129 mEq per liter of blood. It is known that the population stand rd deviation of adult sodium levels is 15 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.05 level of significance, that the population mean adult sodium level differs from that given in the textbook? 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.) (a) State the null hypothesis Ho and the alternative hypothesis H1. P Ho : H = 139 S H, : H # 139 Un (b) Determine the type of test statistic to use. =0 050 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) *0 00 d) Find the two critical values. (Round to three or more decimal places.)
