To test this claim, a random sample of 36adult patients is evaluated. The mean sodium level for the sample is 142 mEq per liter of blood. It is known that the population standarddeviation of adult sodium levels is 13 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.1 level ofsignificance, 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 alist of formulas.)

A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach. Sample mean = 43.9 s = 5.3 n = 15 α = 0.05 H0: µ = 32.6 H1: µ ≠ 32.6 The decision is to the null hypothesis. (Enter R if you reject and enter F if you fail to reject)
