Find a 95% confidence interval for the population mean μ of total calcium in this patient’s blood.

Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma.† Over a period of months, an adult male patient has taken seven blood tests for uric acid. The mean concentration was x = 5.39 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with σ = 1.93 mg/dl. Find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (Round your answers to two decimal places.)   lower limit upper limit margin of error   What conditions are necessary for your calculations?

Hemoglobin is a protein in red blood cells that transports oxygen from the lungs to the body's tissues. People with less than 12 grams of hemoglobin per deciliter of blood (g/dl) are anemic. A public health official in Oklahoma suspects that the mean hemoglobin of children in his city is different than 12. (a) µ represents the population mean of children in Oklahoma. (b) State the hypotheses (Ho & Ha) for a test to verify the public health official's belief. (c) State what the parameter u in your hypotheses is.
