Researchers are trying to estimate the proportion of patients trying a new experimental drug who experience a skin rash as a side-effect. 245 patients took this drug as part of early research, and these 245 patients are considered representative of the population who would take this drug in the future. 2.86% of these patients reported a skin rash. We would like to construct a 90% confidence interval for the proportion of potential drug users who would develop a skin rash.

What would be the standard error for our sample proportion, using the information we have from our sample to estimate that? Round to 3 decimal places

a 90% confidence interval will go 1.65 standard errors out in either direction. Calculate the lower bound of this 90% confidence interval for the true proportion of drug users who experience a skin rash as a side effect

In the US, the Federal Trade Commission (FTC) is tasked with collecting information from consumers and passing on this information to other administrative bodies and policy makers.While the FTC cannot resolve individual complaints, it aggregates this information and passes it on to relevant agencies so that other agencies and policy makers can formulate laws and regulations.

You went to a used car dealer and purchased a used car (“as-is”) without a warranty contract. Let’s say that you cut them a check for $2500 and drove it off the lot. Within 20 minutes of driving it, the car’s engine dies. You take it to your mechanic, who tells you that the timing belt failed and the engine seized as a result. You now need a brand new engine (worth over $3000)

How might you act to resolve this issue? Are there any laws or regulations that could protect your rights in this situation? Are there any governmental bodies that might help you with this situation? Are there any state or federal governmental representatives that might help you in this situation or even prevent such situations from happening to someone else in the future?

A Rankine power cycle with reheat uses water as the working fluid. The inlet conditions of the
first stage turbine are 14MPa and 600C. All the turbines are known to have isentropic
efficiency of 85%, however the pump is assumed as an isentropic pump. If the maximum
temperature is kept at 600C and the condenser pressure is 6 kPa, by constructing a suitable
plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three
reheat pressures between 2 to 12 MPa)
Note: You may construct the plot on Microsoft Excel or manually on a graph paper. However,
all the calculations involved must be performed manually, in details and must be shown clearly.

Write a Java method that removes any duplicate elements from an ArrayList of integers. The method has the following header(signature):

public static void removeDuplicate(ArrayList<Integer> list)

Write a test program (with main method) that prompts the user to enter 10 integers to a list and displays the distinct integers separated by exactly one space. Here is what the input and output should look like:

     Enter ten integers: 28 4 2 4 9 8 27 1 1 9

     The distinct integers are 28 4 2 9 8 27 1

Problem 5-1A Perpetual: Alternative cost flows LO P1 [The following information applies to the questions displayed below.] Warnerwoods Company uses a perpetual inventory system. It entered into the following purchases and sales transactions for March. Date Activities Units Acquired at Cost Units Sold at Retail Mar. 1 Beginning inventory 70 units @ $50.40 per unit Mar. 5 Purchase 210 units @ $55.40 per unit Mar. 9 Sales 230 units @ $85.40 per unit Mar. 18 Purchase 70 units @ $60.40 per unit Mar. 25 Purchase 120 units @ $62.40 per unit Mar. 29 Sales 100 units @ $95.40 per unit Totals 470 units 330 units Problem 5-1A Part 1 Required: 1. Compute cost of goods available for sale and the number of units available for sale. 2. Compute the number of units in ending inventory. Compute gross profit earned by the company for each of the four costing methods. For specific identification, the March 9 sale consisted of 50 units from beginning inventory and 180 units from the March 5 purchase; the March 29 sale consisted of 30 units from the March 18 purchase and 70 units from the March 25 purchase. (Round weighted average cost per unit to two decimals and final answers to nearest whole dollar.)

(YOU don't need to write the client class I already have it, just need this)

You are provided with Main.java that is a client for this program.

You will create THREE files-- GameCharacter.java, ShieldMaiden.java, and Dragon.java

First: You must Create an interface called GameCharacter WITH JUST PROTOTYPES, NO IMPLEMENTATIONS

A GameCharacter has a few functions associated with it

1) takeHit: decreases the character's health. It should return an int representing damage taken (hit points)

2) heal: increases the character's health. Should return an int representing amount healed (i.e. hit points)

3) getHealth: returns the total current health the character has (i.e. hit points)

4) isAlive: determines if the character is dead. Should return true if the character is dead, and false if not.

Second: Then create two classes. One should be named Dragon, and the other should be named ShieldMaiden (i.e. warrior) that IMPLEMENT Game Character. Give them each private variables for health. The constructor should take in an initial amount to set health to.

Third: Implement the interface functions for these two classes (Dragon and ShieldMaiden). To make the game more interesting, the dragon's takeHit should hurt the dragon a random number from 10 to 20 inclusive and the ShieldMaiden's takeHit should hurt the shieldMaiden a random number from 15 to 25 inclusive. Furthermore, the dragon's heal should only heal the dragon a random number from 1 to 10 inclusive but the ShieldMaiden's heal should heal the ShieldMaiden a random number from 8 to 20 inclusive. A character is dead when they get negative health.
