The complete question is as follows:
The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?
Answer: The 95% confidence interval about the mean is 
.
The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.
We follow these steps to arrive at the answer:
Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.
The formula for the confidence interval about the mean is:
In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.
The Critical Value of Z at the 95% confidence level is 1.96.
Substituting the values in the question in the equation above we have,
Answer:
Explanation:
a) since MR=MC, then 15-2Q=3+Q. So, the monopolist produce Q=4
price P=15-Q=10-4=6
profit=6*3-TC=18-(3+4+0.5*4^2)=3
b)since the P=6=6, domestic production will stay the same. The domestic consumption will stay the same. For Wilknam, it will import soccer balls.
c)yes, it holds that Wiknam will be an importer. Because the price for domestic production is 6 which is same as the world price 6.
d)Since the price within country is the same with price out of country, and also, MC=3+Q=7>6, Wiknam will import soccer balls. The monopolist market will become a competitive market.Even though the price won't change,the product will be of high quality and so on. The market will become more equilibrium.
Well 50% of 50,000 is 25,000 so I’d say make sure your cars don’t go above 15,000 a Year cause Car(s)
