The Wrigley Company, manufacturer of Skittles brand fruit candies, is considering adding a new flavor to the "rainbow" of flavors in a Skittles bag: passion peach. To test if America will like the new flavor, Skittles will do a taste test random sample of size n = 140 at a Peoria grocery store. In all of the other taste tests done so far in the United States in other markets, the proportion of the population who like the new flavor = 0.69. Use Table 1. |
| a. |
Calculate the expected value and the standard error for the sampling distribution of the sample proportion of tasters in Peoria who will like the new flavor. (Round "expected value" to 2 decimal places and "standard deviation" to 4 decimal places.) |
| Expected value = .69 | |
| Standard error = .0391 | |
| b. |
What is the probability that the sample proportion of the tasters in Peoria who like the new flavor is between 0.60 and 0.80? (Round final answer to 4 decimal places.) |
| Probability |
| c. |
What is the probability that the sample proportion or the tasters in Peoria who like the new flavor is less than 0.60? (Round final answer to 4 decimal places.) |

Medical professionals can find relationships between variables. The more you drink alcohol, the less functionality of your liver. The less carbohydrates a person intakes, the lower their Body Mass Index. Data can be collected and organized as an ordered pair (x, y). The data can be analyzed to determine the type and strength of a correlation and to calculate a regression line in order to make a prediction. Use the internet to find a data set of ordered pairs. Key terms to search: Free Public Data Sets and Medical Data Sets. Something that is current and in the United States of America, please ? Create a Post: Introduce your Data Set and Cite the Source. Which would be the independent variable, and which would be the dependent variable? Without drawing a scatter plot, would you expect a positive, negative or no correlation? Explain. Would you categorize your data to have a strong or weak correlation? Why? What would the r2 value tell you about the data that you selected? What is the equation of the regression line? Use the regression line to make a prediction about the data you collected.

Question: Environmental fate of medications Medications can enter wastewater management systems either thro... (1 bookmark) Environmental fate of medications Medications can enter wastewater management systems either through human excretions or through improper disposal. Many medications are not effectively treated by current wastewater management processes and therefore are discharged by wastewater treatment plants. Antidepressants are some of the most commonly prescribed medications in the United States, and many antidepressants are not effectively managed by wastewater treatment plants. a. A wastewater treatment plant discharges to Boulder Creek in Colorado at a rate of 64 million L/day, and the stream flow, upstream of the wastewater discharge point, is 1110 L/s. If the concentration of the antidepressant venlafaxine (Effexor) measured in the creek water is 10 ng/L, what is the mass discharged per day from the wastewater treatment plant, assuming that there are no sources other than the wastewater treatment plant, and assuming that the drug rapidly equilibrates among sediment, fish, and water? What is the concentration of the medication in the wastewater treatment plant effluent?

Part I: Explain why any cell in the body can become any cell type of the body. Cancer occurs when the cell cycle becomes unregulated and grows out of control. Why do you think there are so many different types of cancer?
Part II: The practice of buying and selling gametes, particularly eggs from fertile women, is becoming increasingly common in the United States and some other industrialized countries.

Develop a Java application using Parboiled library to write a parser for a customer form. Your program should include a grammar for the parser and display the parse tree with no errors.
The customer form should include the following structure:
First name, middle name (optional), last name
Street address, city, state (or province), country
Phone number
Rules
• First name, middle name and last name should start with an uppercase letter followed by lower case letters. Middle name is an optional input meaning such an input may or may not exist. • The street address can include any type of letters or numbers. There is no lowercase/uppercase restriction either.
• The city name should start with an uppercase letter followed by lowercase/uppercase letters.
• The state or province should start with an uppercase letter followed by lowercase/uppercase letters.
• The country name should start with an uppercase letter followed by lowercase/uppercase letters.
• The phone number should begin with area code in parenthesis, followed by a space, three digits, a hyphen, and four digits.
Example:
John Doe

he National Science Foundation collects data on the research and development spending by universities and colleges in the United States. Here is the data for the years 2008 - 2011:
|
Year |
2008 |
2009 |
2010 |
2011 |
|
Spending (billions of dollars) |
51.9 |
54.9 |
58.4 |
62.0 |
(a) Draw a scatterplot that shows the increase in research and development spending over time. Try to be as accurate as you can with your scatterplot. You may use Excel to help guide you. Does the pattern suggest that the spending is increasing linearly over time?
(b) Find the equation of the least-squares regression line for predicting spending from year. Use Excel to help you. Add this line to your scatterplot.
(c) For each of the four years, find the residual.
(d) Write the regression model for this setting. What are your estimates for the slope and y-intercept in this model?
(e) Use the least-squares regression equation to predict research and development spending for the year 2013 (assume year 2008 is x = 1 , year 2009 is x = 2 , etc.). The actual spending for 2013 was $63.4 billion. Add this point to your plot, and comment on why your equation performed so poorly.
