B is the correct answer. In the referendum process only new laws or recent amendments to existing laws are considered. They allow citizens of many U.S. states - especially in the West - to place new legislation on a popular ballot, or to place legislation that has recently been passed by a legislature on a ballot for a popular vote, being thus a type of direct democracy.
A test (such as an iq test) that accurately measures that it is intended to measure is highly valid.
An intelligence test's numerical result is known as the intelligence quotient, or IQ. It demonstrates how a person's IQ score, as determined by the exam, compares with others of a similar age.
Weiten asserts that "IQ tests are reliable indicators of the type of intellect required to perform effectively in academic tasks. IQ test are highly valid if it measure accurately
The validity of IQ tests, however, is in doubt if intelligence is to be measured broadly. The usefulness of IQ as a measure of intelligence overall has been contested by certain scientists.

Answer:
Mean of sampling distribution=3.5
Standard error of sampling distribution=0.219
Explanation:
We know that
The average of catching fish per fishing trip=μ=3.5
and
The standard deviation of catching fish per fishing trip= σ=1.2.
We have to find the mean and standard error of sampling distribution of 30 fishing trips i.e. μxbar=? and σxbar=?
Mean of sampling distribution=μxbar=μ=3.5
Standard error of sampling distribution=σxbar=σ/√n
Standard error of sampling distribution=σxbar=1.2/√30
Standard error of sampling distribution=σxbar=1.2/5.4772
Standard error of sampling distribution=σxbar=0.219
Thus, the mean and standard error for a sampling distribution of 30 fishing trips are 3.5 and 0.219.
The correct answer is B) As a way to transport goods and people.
Rivers were important to people migrating west "As a way to transport goods and people."
With the Westward expansion, the American people started to settle in the western portion of the territory. Rivers played a major role in the exánsion because they served As a way to transport goods and people.
Let's have in mind that US President Thomas Jefferson had ordered the purchase of the Louisiana Territory owned by the French. So in 1803, after the purchase, Thomas Jefferson ordered the Lewis & Clark expedition to explore the western territories. The Expedition lasted 3 years. After that time President Jefferson was briefed about the findings and that is when he authorized the westward expansion.
