Which quadrant is (8, -1) in?
2 answers:
Its easiest to do this if you look at a picture of the 4 quadrants. The 4 quadrants are numbered counterclockwise, starting the with top right quadrant (see picture 1).
Plot/visualize (8, -1) on the coordinate plane (see picture 2). x=8, so it'll be to the right of y-axis. y=-1, so it'll be below the x-axis. That puts (8, -1) in Quadrant IV.
The answer is D) IV.

Answer:
The "df" stands for "degrees of freedom", and represents the number of independent observations in a set of data.
Its value in this case is df=32.
Step-by-step explanation:
The sample is of size n=33.
As we do not know the population's standard deviation, we use as estimate the sample's standard deviation. Because of this, we use the t-statistic in place of the z-value.
The "df" stands for "degrees of freedom", and represents the number of independent observations in a set of data (the data in this case is the sample of 33 video games).
In one-sample tests, the degrees of freedom are calculated as:
