Answer:
(a)
(b)
B. The sample is too small to make judgments about skewness or symmetry.
Step-by-step explanation:
Given:
Solving (a):
First, calculate the difference between the recorded TBBMC for both operators:
The last row which represents the difference between 1 and 2 is calculated using absolute values. So, no negative entry is recorded.
The mean is then calculated as:
Next, calculate the standard deviation (s).
This is calculated using:
So, we have
Solving (b):
Of the given options (A - E), option B is correct because the sample is actually too small
Answer:
Option (D)
Step-by-step explanation:
Coordinates of the points J, E and V are,
J → (-4, -5)
E → (-4, -3)
V → (-1, -1)
This triangle is translated by the rule given in the question.
Coordinates of the image will follow the rule,
(x, y) → [(x + 2), (y + 4)]
following this rule coordinates of the image triangle will be,
J(-4, 5) → J'(-2, -1)
E(-4, -3) → E'(-2, 1)
V(-1, -1) → V'(1, 3)
Therefore, points given in the option (D) will be the answer.
