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:
3000 + 500 + 60 = 3560

Step-by-step explanation:
Answer:
y is B. 82 degrees (and for extra, x is 54 degrees)
Step-by-step explanation:
The angles shown are complementary, which means they equal 180 degrees. Subtract 73 from 180 to get 107 degrees for the other angle in this set. After that subtract 25 from 107 to get y, which is 82 degrees.
(For x, just subtract 19 from 73 to get 54 degrees.)
