Answer: 59.342
Step-by-step explanation:
The chi-square critical values are used to find the confidence interval for σ.
Left critical value = 
[i.e. chi-square value from chi-square table corresponding to degree of freedom n-1 and significance level of 
]
To find : left critical value for 95% confidence interval for σ with n = 41.
Significance level : 
degree of freedom = 41-1=40
Now, the left critical value for 95% confidence interval for σ with n = 41 is the chi-square value corresponding to degree of freedom n-1 and 
=59.342 [from chi-square table ]
Answer:
There are 180 students at the school
Step-by-step explanation:
If 10% of the students like the color purple, then 100-10 = 90% do not like the color purple.
Students * percentage that do not like = students that do not like
students * 90% = 162
Change to decimal form
students *.90 = 162
Divide each side by .90
students *.90/.90 = 162/.90
students = 180
There are 180 students at the school
We Know That This Number Is:
Two-Thousand-Seven-Hundred-Eighty-Three.
So, This tells Us That The 2 Is The Thousandths Place.
So, We Also Know That The Value Of 2 In The 2nd One Is 200. This Means That The value of the first one is 10 times larger than the value of the 2 in the second one!
Tan=o/adj
Tan=60/b
B=60/tan(68)
I don't have a calculator on me but you should be able to do it from there
They would have 2 because is it 10:1 just double it to be 20:2
