Answer:
Q = 435/22.5 = 19 streetlights
Explanation:
Since the streetlights is apublic good
Obtaining the market demand curve by adding them vertically
P = 20*20Q - 20*Q
P = 5*( - 5*Q/2
hence
P = 445 - 22.5Q
Socially optimal number of street lights
MB20 + MB5 = MC
400 - 20Q + 45 - 2.5Q = 10
22.5Q = 435
Q = 435/22.5 = 19 streetlights
This means that the research shows that 95% of the yield is between 118 to 130 bushels per acre. The mean is 124 bushels per acre and the margin of error is 6 bushels per acre.
<h3>
Confidence interval</h3>
Given that 95% confidence interval for the true mean yield is 118 to 130 bushels per acre.
This means that the research shows that 95% of the yield is between 118 to 130 bushels per acre. The mean is 124 bushels per acre and the margin of error is 6 bushels per acre.
Hence:
μ ± E = (118, 130)
where μ is mean and E is margin of error
μ - E = 118 (1)
Also:
μ + E = 130 (2)
From both equations:
μ = 124, E = 6
The mean is 124 bushels per acre and the margin of error is 6 bushels per acre.

Answer:
The probability that neither of both stocks increase is 0,14
Explanation:
The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.
The data we have is the probability that Stock A or B increase, we are looking for the probability that neither occur, so we have to use the complement of each one.
Complement of Stock A =1-0.54=0.46
Complement of Stock B =1-0.68=0.32
If we want to know the probability of both events happening we have to multiply both complements.
Probability that neither of these two events will occur= 0.46 x0.32= 0,1472
