Answer:
The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.

The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.
A normal distribution describes how the values of a variable are distributed. It is a probability distribution that is symmetrical about the central value or the mean, i.e. 50% of data are found to the left and right of the mean respectively. Most of the data are clustered around the mean, i.e. they occur or are found near the mean than far away from the mean. The graph form of a normal distribution will appear as a bell curve. In a normal distribution, mean = mode = median.
The Central Limit Theorem states that irrespective of the underlying distribution of a sample, when a variable does not follow a normal distribution, repeated random samples from the population will give sample means they are normally distributed. This means that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger.
Answer:
Humans and many other animals have monogastric digestive systems with a single-chambered stomach. Birds have evolved a digestive system that includes a gizzard where the food is crushed into smaller pieces.

Answer:
The options are missing, they are:
A) Extranuclear inheritance
B) Maternal effect
C) Imprinting
D) Nuclear
E) Epigenetic
The answer is A
Explanation:
Inheritance has been said to have to do with genes stored in the genetic material (DNA), which is collectively housed by a membranous nucleus in eukaryotic cells. However, some inheritance pattern has been found to not involve the genes in the nucleus, instead they involve genes present in cellular organnelles like mitochondria and plastids in plant cells. This pattern of inheritance is called EXTRANUCLEAR inheritance.
One difference between nuclear and extranuclear inheritance is that unlike nuclear inheritance that involves two parents, only one parent transfers genetic material to offsprings i.e. uniparental.
Fossils are ancient bones from beyond humanoid exsistence they are often found under lots of soil and minerals because of the asteroids that killed it and many years of just minerals pilling on top of it
