Answer: test statistic.
Step-by-step explanation:
The chi-square ( ) test is a non-parametric statistical test(also known as Goodness of fit test) which is used to determine if a distribution of observed frequencies differs from the expected frequencies.
Chi-square statistic uses either nominal (categorical) or ordinal level data.
Hence, When determining how well an observed set of frequencies fits an expected set of frequencies, the test statistic is test statistic.
Answer:
132
Step-by-step explanation:
Divide it into 2 shapes : a triangle and a rectangle.
The triangle's base length is 20-(8+6) = 6
The height is 10-6 = 4
The triangle's area = 6*4/2 = 12
The rectangle's area is 6 * 20 = 120
Add the two together, and you get 12+120 = 132
We know that a = b and c = 30
Since b + 30 = 90, we know b = 60.
That means a = 60
a = 60
b = 60
c = 30
In order to do this, you need to visualize that
x = 6 would be a vertical line on point (6,0), also if it was y=6 , it would be a horizontal line on point (0,6)
Then draw the lines connecting point (6,1) , (6,2) , (6,3) , etc
Hope this helps
3 units right. The x increases by three each time, and the x axis is horizontal and going right means it goes up.
