Transcribed Image Text:(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.
Ο Α. H : μ = 4.55,
Ο B. H : μ < 4.55,
OC. Ho

H@ :μ < 4.55
Η : μ = 4.55

Ο F. H : μ = 3.75, Η : μ + 3.75
(b) According to the Merck Veterinary Manual, the
average resting heart rate for a certain type of sheep dog
is 115 beats per minute (bpm). A Montana farmer notices
his aging sheep dog has been acting more lethargic than
usual and wonders if her heart rate is slowing. He
measures her heart rate on 15 occasions and finds a
sample mean heart rate of 118.2 bpm.

(c) The mean height of all adult American males is 69
inches (5 ft 9 in). A researcher wonders if young
American males between the ages of 18 and 21 tend to
be taller than 69 inches. A random sample of 100 young
American males ages 18 to 21 yielded a sample mean of
71 inches.
