For each of the situations described, state whether the sampling procedure is simple random sampling, stratified random sampling
aleksklad [387]

Answer:

The sampling method applied is Cluster sampling.

Step-by-step explanation:

A cluster sampling method is the type of sampling where first the entire population is divided into homogeneous groups. Then a random sample of these groups are selected.

After selecting a sample of groups, a random sample of fixed size is selected from each group.

In this case all freshmen are first divided into 30 sections, then 4 random sections are selected and the students in those 4 sections are sampled.

The sampling method applied is Cluster sampling.

The temperature at a mountain base camp was −4 degrees Celsius on Saturday. Sunday morning, the temperature was 2 degrees Celsiu
elixir [45]
Well when you go lower with negatives the number gets bigger so
It was -4C then it was 2 lower which is -6C then it got lower again in the evening by 1 degree celcius which gives the answer -7 degrees celcius

Consider the following discrete time process: at integer times, a marble arrives which can be one of m colors. Each color is equ
Flauer [41]

Answer:

Below are the responses to the given question:

Step-by-step explanation:

Let X become the random marble variable & g have been any function.

Now.

For point a:

When X is discreet, the g(X) expectation is defined as follows

Then there will be a change of position.

E[g(X)] = X x∈X g(x)f(x)

If f is X and X's mass likelihood function support X.

For point b:

When X is continuing the g(X) expectations is calculated as, E[g(X)] = Z ∞ −∞ g(x)f(x) dx, where f is the X transportation distances of probability.If E(X) = −∞ or E(X) = ∞ (i.e., E(|X|) = ∞), they say it has nothing to expect from EX is occasionally written to stress that a specific probability distribution X is expected.Its expectation is given in the form of,E[g(X)] = Z x −∞ g(x) dF(x). , sometimes for the continuous random vary (x). Here F(x) is X's distributed feature. The anticipation operator bears the lineage of comprehensive & integral features. The superposition principle shows in detail how expectation maintains equality and is a skill.

the measure of angle a is 16 degrees greater than the measure of angle b. the tow angles are complementary. find the measure of
Fudgin [204]
This is a system of equations problem.  Set up the 2 equations like so: If the angles are complementary then they add up to 90, therefore, a + b = 90.  We also know that a is 16 more than b.  The word "is" means equals and "more" is addition.  Therefore, a is 16 more than b is "a = b + 16".  Now sub in that value of a (b + 16) into the first equation and solve for b.  Then back-substitute to solve for a. (b + 16) + b = 90 so 2b + 16 =  90 and 2b = 74.  So b = 37.  If b = 37, then a + 37 = 90 and a = 53.  Check yourself to make sure that 37 + 53 add up to equal 90 (they do, just get used to checking yourself for accuracy).
