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 variable of interest of a population, and for this case we know the following conditions
Where
and
And for this case we select a sample size of n= 15. and we want to know the distribution for the sample mean
. We can assume that the distribution for
is approximately normal and given by:

Asuming that the distribution for X is also approximately normal. So then the parameters are:


Answer:
d option
Step-by-step explanation:
Area of rectangle = length × breadth
Placing the values,
143 m² = length × 6.5 m
length = 143 m²/6.5 m = 22 m.

1. A, Because you're able to take any point on that plane and use it to name it.
2. b (not really sure how to explain....)
3. not sure.
4. d, since e is under plane p
