1. The level of various substances in the blood of kidney dialysis patients is of concern....
Question 9 [10 pts) Patients with chronic kidney failure may be treated by dialysis, in which a machine removes toxic wastes from the blood, a fundction normally performed by the kidneys. Kidney failure and dialysis can cause other changes, such as retention of phosphorus, that must be corrected by changes in diet. A study of the nutrition of dialysis patients measured the level of phosphorus in the blood of several patients on six occasions. Here are data for one patient...
A study of the nutrition of dialysis patients measured the level of phosphorus in the blood of a patient on 30 occasions. The mean phosphorus level for this patient was 5.2 mg/dL and a population standard deviation for all dialysis patients of 1.0 mg/dL. Is there evidence that this patient’s true mean phosphorus level significantly exceeds 4.8 mg/dL, the upper end of the “normal” range? 5. For the story above, (a) state the hypotheses, (b) calculate the test statistic and...
Testing blood cholesterol. The distribution of blood cholesterol level in the popnudation of young men aged 20 to 34 years is close to Nonal with mean 188 milligrams per deciliter (mg/dL) and standard deviation 41 mg/dL. You measure the blood cholesterol of 14 young men aged 20 to 34 years who have completed at least one marathon. The mean level is x = 172 mg/dL. Assume that σ is the same as in the general population. Use this information to...
Sheila's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if the glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Sheila's measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with...

Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. In a test to screen for gestational diabetes, a patient is classified as needing further testing for gestational diabetes if the glucose level is above 145 milligrams per deciliter (mg/dL) one hour after a sugary drink. Shelia's measured glucose level one hour after the sugary...
