To test this claim, arandom sample of 20 adult patients is evaluated. The mean sodium level for the sample is 137 mEq per liter of blood. It isknown that the population standard deviation of adult sodium levels is 15 mEq. Assume that the population is normallydistributed. Can we conclude, at the 0.05 level of significance, that the population mean adult sodium level differs from thatclaimed 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. (Ifnecessary, consult a list of formulas.)

Solve the problem. A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are Ho: p = 0.6 and Ha: P < 0.6. The test statistic and p-value for the test are z = -1.51 and p-value = 0.0655. For a significance level of a = 0.05, choose the correct conclusion regarding the null hypothesis. O None of these.
