Answer: 0.0062
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Assume that age of people in the country is normally distributed.
The formula to calculate the z-score :-
For x = 32
The p-value =
Hence, the the probability that the average age of our sample is at least =0.0062
Answer:
These are the rules of rotation for geometry.
1) 90° clockwise rotation: (x,y) becomes (y,-x)
2) 90° counterclockwise rotation: (x,y) becomes (-y,x)
3) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
4) 270° clockwise rotation: (x,y) becomes (-y,x)
5) 270° counterclockwise rotation: (x,y) becomes (y,-x)
Step-by-step explanation:
I hope this helps! I also added a picture to make this more clear.
