(a) A certain type of hummingbird is known to have an average weight of 4.55 grams. A researcher wonders if hummingbirds (of this same type) living in the Grand Canyon differ in weight from the population as a whole. The researcher finds a sample of 30 such hummingbirds from the Grand Canyon and calculates their average weight to be 3.75 grams. A. Ho : = 4.55, Ha:i< 4.55 B. H, : 4 = 4.55, H, : H* 4.55 C.

A researcher wonders if young American males between the ages of 18 and 21 tend to be taller than 69 inches.
