An old medical textbook states that the mean sodium level for healthy adults is 141 mEq per liter of blood. A medical researcher believes that, because ofmodern dietary habits, the mean sodium level for healthy adults, µ, now differs from that given in the textbook. A random sample of 150 healthy adults isevaluated. 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 13mEq. Can we conclude, at the 0.01 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 H, and the alternative hypothesis H .H, :0H, :0(b) Determine the type of test statistic to use.|(Choose one) ▼O=0(c) Find the value of the test statistic. (Round to three or more decimal places.)O#0O

Given: n= 150.0 ,x̄= 142.0 ,σ= 13.0 µ= 141.0 ,significance level(∝)= 0.01

It takes an average of 9.1 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 49 injured patients to immediately tell the truth about the injury and noticed that they averaged 8 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.31 minutes. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b.

Low-density lipoprotein, or LDL, is the main source of cholesterol buildup and blockage in the arteries. This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123 mg/dL and a standard deviation of 41 mg/dL. If an individual's LDL is at least 1 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 1 or more standard deviations above the mean? Use the 68–95–99.7 rule. (Enter your exact answer as a whole number.) percentage %
