Determine the critical value for a right-tailed test of a population mean at the α = 0.01 level of significance with 8 degrees of freedom.

Construct a 95% confidence interval for the population mean, μ. A sample of 20 part-time workers had mean annual earnings of $3120 with a standard deviation of $677. Round to the nearest dollar.

A final exam in Math 160 has a mean of 73 with standard deviation 9.8.  Assume that a random sample of 24 students is selected and the test score of the sample is computed.  Assuming the scores are normally distributed, what percentage of sample means are between 71 and 75?

Which is a shock compensation mechanism? (H21)

An anastomosis provides an alternate path of regional blood supply in case the primary supply vessel is obstructed or damaged. (A9)

Kwashiorkor is a condition seen in children living in regions of famine. The children are gaunt, have very thin limbs, and an extremely enlarged abdomen due to ascites.  Ascites is the accumulation of fluid in the peritoneal cavity. Explain why ascites occurs in these malnourished children.
