(1,4) sorry that’s probably not right lmaaoaoo
Answer:
The initial value is 20.
Step-by-step explanation:
The initial value just means the value that the graph begins at (or the value of the y-intercept) so the initial value would be 20. Hope this helped :)
Answer:
x=4
Step-by-step explanation:
Answer: (80% , 85%)
Step-by-step explanation:
We know that, confidence interval for population proportion is given by :-
(p-E , p+E)
, where p = sample proportion , E = Margin of error.
Given : Proportion of elementary school teachers who are female = 82%.
The article also states the maximum error of their estimate = 3%.
Then, the 90% confidence interval for the proportion of elementary school teachers who are female will be :
(82%-2% , 82%+3%)
= (80% , 85%)
Hence, the resulting 90% confidence interval for the proportion of elementary school teachers who are female = (80% , 85%)
A set of data is given. It is required to find the first, second, and third quartile.
The given data is:
![2,8,9,10,14,15,16,16,17,17,20](https://tex.z-dn.net/?f=2%2C8%2C9%2C10%2C14%2C15%2C16%2C16%2C17%2C17%2C20)
Recall that the lower quartile Q₁, or the first quartile, is the median of the lower half of the data in a set.
The lower half is:
![2,8,9,10,14](https://tex.z-dn.net/?f=2%2C8%2C9%2C10%2C14)
Find the median of the lower half to get the first quartile, Q₁:
Hence, Q₁=9.
Recall that the second quartile Q₂ is the same as the median of the data.
The median is the middle element or the mean of two middle elements in a numerical data set with the elements ordered by their value.
Notice that the middle number is 15.
Hence, second quartile Q₂=15.
The upper quartile Q₃, or the third quartile, is the median of the upper half of the data in a set.
The upper half of the data is:
![16,16,17,17,20](https://tex.z-dn.net/?f=16%2C16%2C17%2C17%2C20)
Calculate the median to find the third quartile, Q₃:
It follows that Q₃=17
