Answer:
(a) H0: mu = 17 vs. Ha: mu < 17
(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
(b) Sample statistic = sample mean ÷ sample size = 16 ÷ 10 = 1.6
<span> gills, fins, and blood.
The three structures and physical entities that almost all fish have:
Gills
Fins
Blood
Almost all fish have gill slits because there is no other way they can breathe underwater without having gills.Fins are used to move around the water and blood delivers oxygen and nutrients.

Answer:
1. Endoneurium covers the myelinated or unmyelinated axons. it is a layer of delicate connective tissue that envelops the myelin sheath of each of the myelinated nerve fiber.
2. Perineurium covers fascicles. It is the connective tissue sheath that envelops fascicle of nerve fibers within a nerve.
3. Epineurium covers nerves. It is the outermost layer of dense irregular connective tissue that envelops the peripheral nerve and multiple nerve fascicles.
Processes that are most important to human life are oxygen, required for cellular respiration, and glucose, a form of sugar that releases energy during cellular respiration.
The best answer is Neoproterozoic era. Neoproterozoic Era is the unit geologic time from 1000 to 541 million years ago. It is the last era of the Precambrian Supereon and the Proterozoic Eon; it is subdivided into the Tonian, Cryogenian, and Ediacaran Periods. It is preceded by the Mesoproterozoic era and succeeded by the Paleozoic era.
