Answer:
If the weight is higher than 5.8886 gr would be considered significantly high
If the weight is lower than 5.6121 gr would be considered significantly low
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
And the best way to solve this problem is using the normal standard distribution and the z score given by:
For the case when z =-2 we can do this:
And if we solve for X we got:
And for the other case when Z=2 we have:
And if we solve for X we got:
If the weight is higher than 5.8886 gr would be considered significantly high
If the weight is lower than 5.6121 gr would be considered significantly low
Here we go ~
1. A circle can be named by their Centre, so here in the diagram it's :
- Circle A
2. Name 4 radii :
Radii are the line segments that joins the centre and boundary of circle.
They are :
- FA
- GA
- BA
- CA
3. 2 Major arcs :
considering two points on a circle, and joining them forms a curve ( you can say part of circumference )
When we consider two points two arcs are formed and the arc with more length is known as Major Arc
That is :
- Major arc ECF
- Major arc BEC
4. A Semicircle :
Semicircle is special arc which is formed when two arcs formed by the points are equals to one another... it's also half the Perimeter of circle.
that is :
- Arc CF is a Semicircle
5. 3 minor arcs :
The arc formed by two points having lesser length is known as minor arc.
that is :
- Arc EF
- Arc BG
- Arc FG
6. 3 Central angles :
Central angles are angles formed by arcs on centre of the circle ~
that is :
- Angle FAB
- Angle BAC
- Angle GAB
7. A diameter :
Diameter is a chord that passes through centre of the circle.
- CF
8. Congruent Angles :
In the given figure, there are two equal/congruent angles that are ~
- Angle BAG and Angle GAF
9. Adjacent arcs :
The arcs that have one common end point are known as Adjacent arcs ~
that are :
- Arc FG and Arc GB
