Rotation: 90 degrees clockwise
Required
Determine A'B'C'
When a point
is rotated 90 degrees in the clockwise direction, the new coordinates is: 
So, we have:

Answer:4
Step-by-step explanation:
Answer:
Null hypothesis is: U1 - U2 ≤ 0
Alternative hypothesis is U1 - U2 > 0
Step-by-step explanation:
The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.
Let U1 = mean sales by type A trainees
Let U2 = mean sales by type B trainees
Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0
This implies that type A training does not result in higher mean weekly sales than type B training.
The alternative hypothesis (H1) is: U1 - U2 > 0
This implies that type A training indeed results in higher mean weekly sales than type B training.
The answer is A.) 5 because it’s the smaller number
The correct answer would be A- as it shows the correct median of 25.5
