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:
Answer:
∠ VWU = 48°
Step-by-step explanation:
Since VW and VU are congruent then the triangle is isosceles with 2 base angles being congruent , that is
∠ VWU = ∠ VUW , then
∠ VWU =
=
= 48°
