question 8

Essay

You will be asked to sketch curves representing the distributions of a set of data, as well as the sampling distributions of the mean under different conditions. You need not get these graphs perfectly correct, but should clearly indicate different aspects of the curves, such as location, variability, and shape. The State Fisheries Department wishes to stock the Styx River with fish, and would like the species to not only survive but thrive. (The "substrate" of a river is an important determinant of the quality of spawning habitat.) The pebble diameters in the river are approximately normally distributed with a mean of 24 mm, and a standard deviation of 8 mm. The Fisheries people will select a random sample of pebbles from the Styx River in an attempt to judge the average pebble size.

The graph below is a relative frequency histogram of the lengths of the gentle Hecate fish in the Styx River, as recorded during a massive fish tagging survey. The mean length for these fish was 0.8 feet. Suppose we were to take a random sample, n = 4, from this population of fish and measure their lengths. Describe the shape, center, and spread of the sampling distribution of . for a sample of size n = 16.
