Answer:
1. If it is true that 60 percent of the trees in a forested region are classified as softwood, 0.015 is the probability of obtaining a population proportion greater than 0.6.
Step-by-step explanation:
Hello!
The historical information indicates that 60% of the forest trees are classified as softwood.
A botanist thinks that the proportion might be greater than 60%, so he tested his belief obtaining:
H₀: p = 0.60
H₁: p > 0.60
p-value: 0.015
You need to interpret this p-value. Little reminder:
The p-value is defined as the probability corresponding to the calculated statistic if possible under the null hypothesis. It represents the % of size n samples from a population with proportion p=p₀, which will produce a measure that provides evidence as (or stronger) than the current sample that p is not equal to p₀.
The correct answer is:
1. If it is true that 60 percent of the trees in a forested region are classified as softwood, 0.015 is the probability of obtaining a population proportion greater than 0.6.
I hope this helps!
Answer:
And we can find this probability using the z table and we got:
Step-by-step explanation:
Let X the random variable that represent the thickness of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the z table and we got:
The answer:
the full question is
ΔABC will undergo two transformations to give ΔA′B′C′. Which pair of transformations will give a different image of ΔABC if the order of the transformations is reversed?
a possible answer for such a question is
A ROTATION 180° CLOCKWISE ABOUT THE ORIGIN FOLLOWED BY A REFLECTION ACROSS THE Y-AXIS
The statement below best describes the value the base 0.86 is that "the car Trevor purchased depreciates at a rate of 86%".
- It should be noted thàt depreciation occurs when we buy an equipment or machine and use it. With time, due to wear and tear or usage, the value reduces.
- The value of the car will not appreciate but rather depreciate. Therefore, the correct option is "the car Trevor purchased depreciates at a rate of 86%".
In conclusion, the correct option is D.
