The Westchester Chamber of Commerce periodically sponsors public service seminars and programs. Currently, promotional plans are under way for this year's program. Advertising alternatives include television, radio, and online. Audience estimates, costs, and maximum media usage limitations are as shown: Constraint Television Radio Online Audience per advertisement 110,000 18,000 30,000 Cost per advertisement $1,500 $250 $500 Maximum media usage 11 21 13 To ensure a balanced use of advertising media, radio advertisements must not exceed 50% of the total number of advertisements authorized. In addition, television should account for at least 10% of the total number of advertisements authorized.

Advertisement Alternatives No of commercial messages Television Radio Online What is the allocation of the budget among the three media? Advertisement Alternatives Budget ($) Television $ Radio $ Online $ What is the total audience reached?

1. Find the appropriate measure of center. Discuss why the chosen measure is most appropriate. Why did you decide against other possible measures of center? 2. Find the appropriate measure of variation. The measure of variation chosen here should match the measure of center chosen in Part 1. 3. Find the graph(s) needed to appropriately describe the data. These may be done by hand and inserted into the Word document. You can also use Excel or a Web Applet to create a Histogram of the chosen data. Graphs can be copied and pasting onto the template. 4. Define the random variable (X) so that your chosen data set represents values of X. 5. Is your chosen random variable discrete or continuous? Explain how you know. 6. Would the Normal or Binomial distribution be a good fit for the underlying sample distribution of X? If one of them is a good fit, state how you would approximate the distribution parameters (Use the mean and standard deviation of the data chosen) 7. If you selected column D, calculate the probability that a flight will depart early or on-time. If you selected column E, calculate the probability that a flight will arrive early or on time using the empirical definition of probability. 8. If you selected column D, calculate the probability that a flight will depart late. If you selected column E, calculate the probability that a flight will arrive late using the empirical definition of probability. 9. For those that selected column D, assume now that the random variable X = Departure Time is exactly normally distributed with mean m= -2.5 and standard deviation s= 23. Compute the probability of a flight arriving late based on this new information. For those that selected column E, assume now that the random variable X = Arrival Time is exactly normally distributed with mean m= -2.5 and standard deviation s= 23.

A local group claims that the police issue at least 60 speeding tickets a day in their area. To prove their point, they randomly select one month. Their research yields the number of tickets issued for each day. The data are listed below. Assume the population standard deviation is 12.2 tickets. At ? = 0.01, test the group’s claim. Make sure to state your conclusion regarding the claim with your reasoning.

7. A local politician, running for reelection, claims that the mean prison time for car thieves is less than the required 4 years. A sample of 80 convicted car thieves was randomly selected, and the mean length of prison time was found to be 3.5 years. Assume the population standard deviation is 1.25 years. At ? = 0.05, test the politician’s claim. Make sure to state your conclusion regarding the claim with your reasoning.

Examine the ideas of Leibniz and Newton related to the foundations of the calculus. Further explore how mathematics evolves and what happens when breakthroughs in mathematical thought happen at the same time and how one thinker gets the credit.

Work out the products of the matrices E, R, R^2,R^3, A, B, C, D,
and verify that these products reproduce the multiplication table for the
symmetries of the square, as expected. (Instead of computing all 64 products,
compute “sufficiently many” products, and show that your computations
suffice to determine all other products.)
