"Suppose that a learning curve us described by the function T(N) = 20/√N Where (T)n is the time in hours to produce the nth unit. a. How much time is required to produce the fourth unit. b. How much time is required to produce the first four units. c. If the cost of labor is $10 per hour, how much money does if cost the to produce the first four units. "

As the confidence level “1 – α” increases, the width of the confidence interval. a. increases b. decreases c. remains the same d. None of the above

Graph the function g(x) = [x (9x – 5) (x – 1)] 4. Calculate the first derivative and critical points.

A bag contains 5 blue balls and 8 purple balls. If 3 balls are chosen randomly and without replacement, form the bag. Let x be the number of blue balls obtained. Then x has a distribution. (a) Poisson (b) Geometric (c) Normal (d) Binomial (e) Hypergeometic  

"1.The following 30 scores on the mathematics portion of the SAT were achieved by a sample of 30 students.   500,510,514,516,519,521,522,522,527,514,528,535,540,542,545,553,555,558,561,571, 572,574,577,578,580,583,584,588,589,592. Construct a dot plot, box plot, and stem-and-leaf display to discuss any patterns in the data set. "

An experiment consists of flipping a fair coin three times and noting the number of heads and tails. A random variable x is defined to be two times the number of heads plus the number of tails. Find E(x), the expected value of x.

"1. Define necrosis and ischemia. 2. What are the body’s two main methods of repairing damaged tissue? "

Graph the function h(x) = x2/3 (x2 -2x – 6). Calculate the first derivative. Calculate critical values and use the first derivative test to show maximums and minimums. Clearly label the critical points and the increasing and decreasing intervals on the graph.

A bag contains 5 blue balls and 8 purple balls. If 3 balls are chosen randomly and without replacement, form the bag. Let x be the number of blue balls obtained. Then x has a distribution. (a) Poisson (b) Geometric (c) Normal (d) Binomial (e) Hypergeometic

Five neighborhoods (NB) all want to raise money for a playground for their kids. The neighborhood that raises the most money will be able to choose the name of the park. To raise money, they all decide to have a bake sale and sell cookies (C), cakes (K), and muffins (M). They plan to sell their bake...

Suppose that 60 percent of the voters in a particular region support a candidate. Find the probability that a sample of 1,000 voters would yield a sample proportion in favor of the candidate within 4 percentage points of the actual proportion

"A fast food restaurant strives to serve 80 customers per hour during its peak lunch hour.  It samples 30 shifts (i.e. 30 peak lunch hours) to determine whether it is meeting this expectation.  The sample mean is 75 customers.  The population standard deviation is known to be...

According to Advertising Age, the average base salary for women working as copywriters in advertising firms is higher than the average base salary for men. The average base salary for women is $67,000 and the average base salary for men is $65,500 (Working Women, July/August 2000). Assume salaries are normally distributed and that the standard deviation is $7000 for both men and women.
