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. (a) What is the level of significance?

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Raw Data) if a researcher would like to determine if there is a significant difference in the "Systolic blood pressure (SBP) "between "Male" and "Female"? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the SBP between Male and Female? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the Systolic blood pressure (SBP) between Male and Female? 2. What is the computed Mean of Male on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places. 3.
