Annual expenditures for prescription drugs was $838 per person in the Northeast of the country. A sample of 60 individuals in the Midwest showed a per person annual expenditure for prescription drugs of $745. Suppose the population standard deviation is $300. Follow the steps below to develop a hypothesis test to determine whether the sample data support the conclusion that the population annual expenditure for prescription drugs per person is lower in the Midwest than in the Northeast.

  1. Formulate the null and alternative hypotheses.  State whether this is a one-tailed test (and if so, upper or lower tail) or a two-tailed test.
  2. Suppose the significance level is . Explain what this means.
  3. Calculate the test statistic. (Hint: Is  known or unknown?)
  4. Calculate the p-value and make a decision to either reject  or to fail to reject .
  5. Calculate the critical value(s). Use the test statistic then to make a decision to either reject  or to fail to reject .
  6. State what your decision means in the context of the problem (prescription expenditure in the Midwest vs. the Northeast).

You believe that capital markets are semi-strongly efficient. McDonald's announces stronger than expected quarterly earnings. What is likely to happen to the share price? Is there a way to profit from the announcement? What if the strong earnings were expected, what would happen to the share price?

Formula 3 =  y( x) = (x^3 - 2x^2 + 5x – 25)/40

In terms of hand calculations, determine the root of Formula 3 given above by using the Newton-Raphson method. Start with an initial guess of xo = -4, i.e., yo = y(-4). Label your successive solution pairs as(xo yo), (x1, y1), (x2, y2)….Work out your solution (at each step) to an accuracy of two places below the decimal point. Your overall solution is to display full detail of every step taken. At the end of your derivation, write a summary table that displays the x, y and dy/dx values for each step along the solution path. Clearly state your final answer and the number of iterations required to reach it.

In an (AC) RLC circuit, does the what is the order of obstruction? Does the inductor, capacitor, or resistor obstruct first? and last? And what are each of them obstructing ( change of current or change of voltage)?

What about in (DC) source?

What happens when the capacitor receives a change in rate of voltage? Does it induce a new current to push back the voltage? I am very confused.

Please show in detail and diagrams.

Thank you

A commuter must pass through five traffic lights on her way to work and will have to stop at each one that is red. She estimates the probability model for the number of red lights she hits (x), as shown below: x 0 1 2 3 4 5 p(x) 0.04 0.23 p 0.1 0.1 0.1 a)Find the probability that she hits at most 3 red lights. Answer to 2 decimal places. b)Find the probability that she hits at least 3 red lights. Answer to 2 decimal places. c)How many red lights she expect to hit? Answer to 2 decimal places. d)What is the standard deviation of number of red lights she hits? Answer to 3 decimal places. e)Let us consider any two consecutive days. What is the chance that she hits exactly two red lights on both days? Answer to 4 decimal places

Let a bowl contain 15 chips of the same size and shape. Only one of those chips is red. Continue to draw chips from the bowl, one at a time at random and without replacement, until the red chip is drawn. Show your work.

a) Find the probability mass function of X, the number of trials needed to draw the red chip.

b) Compute the mean and variance of X.

c) Determine P(X <= 10).

John Smith is 16 years old; his parents purchase a red Volkswagen bug for his birthday. He does not like the car because he wanted a red Porche. The parents take the car back to the dealership. The parents tell the dealership this contract is void because our son lacked capacity to enter into this contract. Are the parents right? Use IRAC format.
