Answer:
The major condition that needs to be satisfied before a t-test is performed that the question satisfies easily is the use of random sampling to obtain sample data.
Step-by-step explanation:
The major conditions necessary to conduct a t-test about a mean include;
- The sample extracted from the population must be extracted using random sampling. That is, the sample must be a random sample of the population.
- The sampling distribution must be normal or approximately normal. This is achievable when the population distribution is normal or approximately normal.
- Each observation in the sample data must have an independent outcome. That is, the outcome/result of each sub-data mustn't depend on one another.
Of the three conditions that need to be satisfied before the conduction of a t-test, the first condition about using a random sampling technique is evidently satisfied.
It is stated in the question that 'A private investigator hired by a competitor takes a random sample of 47 games and tries to determine if there are more than 7 glitches per game'.

It is nonlinear because X is being raised to the second power
The answer on this question is D
Answer:

Step-by-step explanation:
There are a couple of ways to solve this, depending on what you already know.
Point-Slope Form
where <em>m</em> is the slope and
is a point on the line.
First, calculate the slope using the two given points
.
.
Fill in the point-slope pattern

There's the equation in slope-intercept form (
).
Slope-Intercept Form
Use
directly.
Find the slope just like the above, so
.
Now, plug one of the points (either one!) together with <em>m</em> into

Now you know the value of <em>b</em>, so the equation for the line is

You do 25,000 divided by 6 is the answer and the remainder would be the cents.
