A magazine includes a report on the energy costs per year for 32-inch liquid crystal display (LCD) televisions.The article states that 14 randomly selected 32-inch LCD televisions have a sample standard deviation of$3.27. Assume the sample is taken from a normally distributed population. Construct 80% confidence intervalsfor (a) the population variance and (b) the population standard deviation σ. Interpret the results.

The sample standard deviation [s] = 3.27The sample variance [s^2] = 10.6929The sample size [n] = 14

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna). (Reference: Hummingbirds, K. Long, W. Alther.) Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and ? = 0.64 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is ? = 4.30 grams. Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.30 grams? Use ? = 0.10.
