Determine whether the samples are independent or dependent. A data set includes systolic blood pressure measurements from each of 230 randomly selected men and 230 randomly selected women. Choose the correct answer below. OA. The samples are independent because there is not a natural pairing between the two samples. OB. The samples are dependent because there is a natural pairing between the two samples. OC. The samples are independent because there is a natural pairing between the two samples. OD. The samples are dependent because there is not a natural pairing between the two samples.
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. Level of significance = .10 Null and alternate hypotheses. - H0: ? = 4.3 g; H1: ? < 4.3 g; left-tailed Sampling Distribution - The standard normal, since we assume that x has a normal distribution with known ?
