Answer:
b. 2.01 < σ < 2.81
Step-by-step explanation:
The 90% confidence interval for the population standard deviation is calculated as:
< σ < 
Where n is equal to 51, s is equal to 2.34,
is 10%,
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of
in the right tail and
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of
in the right tail.
So, replacing n by 51, s by 2.34,
by 67.50 and
by 34.76, we get that the The 90% confidence interval is equal to:
< σ <
2.01 < σ < 2.81
Answer:
A':A = 1742:7
Step-by-step explanation:
Applying,
A' = L'W'............... Equation 1
Where A' = Area of the window, L' = Length of the window, W' = Width of the window.
From the question,
Given: L' = 312 ft, W' = 134 ft
A' = (312×134)
A' = 41808 ft²
Similarly,
A = LW.................. Equation 2
Where A = Area of the image of the window, L and W is thw length and width of the image of the window
Given: L = 12 ft, W = 14 ft
Therefore,
A = 12×14
A = 168 ft²
Therefore the ratio of A' to A = 41808:168 = 1742:7
A':A = 1742:7
1.8 because it’s division just divide 2/2.8 and the answer is
1.8
