*MiniTab Is Required for this question** Suppose that a precise measuring device for new hair growth has been developed and is used in the experiment described in exercise 1922. The percentages of new hair growth for the 30 pairs of men involved in the experiment were recorded. Do these data allow the chemist to conclude that drug B is more effective?

We consider the experiment of picking a point at random from the interval (0, 1). The sample space for this experiment is the interval (0, 1). We consider three sequences of events in this sample space En = ( 1 n , 1) Fn = (1 − 1 n , 1), Gn = ( 1 2 − 1 2n , 1 − 1 2n ), n positive integer. (a) Is (En) ∞ n=1 increasing, decreasing, both, or neither? (b) Is limn→∞ En defined? If so, what is it (express your answer in interval notation). (c) Is (Fn) ∞ n=1 increasing, decreasing, both, or neither? (d) Is limn→∞ Fn defined? If so, what is it (express your answer in interval notation). (e) Is (Gn) ∞ n=1 increasing, decreasing, both, or neither? (f) Is limn→∞ Gn defined? If so, what is it (express your answer in interval notation).

An article in the New England Journal of Medicine described a randomized experiment that investigated the effectiveness of two medications for nausea in patients undergoing chemotherapy treatments for cancer. In the experiment, 157 patients were divided at random into two groups. One group of 78 patients were given a standard anti-nausea drug called prochlorperazine, while the other group of 79 patients received delta-9-tetrahydrocannabinol (i.e., THC, the active ingredient in marijuana). Both medications were delivered orally and no patients were told which of the two drugs they were taking. The observed response was whether or not the patient experienced relief from nausea when undergoing chemotherapy. 16 of the patients taking prochlorperazine experienced relief from nausea, while 36 of the patients taking THC experienced relief from nausea. Conduct a significance test to determine if there is evidence that there is a difference in the effectiveness of the two drugs

and analyze each of these experiments. You will prepare two separate analyses; for each analysis, include the following:

A brief summary of the study

A one paragraph explanation of   the background in the field leading up to the study, and the reasons the researchers carried out the project.

The significance of the study to the field of psychology

A brief discussion of supportive or contradictory follow-up research findings and subsequent questioning or criticism from others in the field  

A summary of at least one recent experiment (within the past two years) that is related to the seminal experiment (Hint: Excellent sources for recent research summaries are the American Psychological Association’s Monitor on Psychology and the Association for Psychological Science).

Business Statement:
The project is about developing an auction Web site. The details are as follows:

BA is an online auction Web site. People can buy and sell items in this Web site. Buyers are people who like to buy items, and sellers are people who like to sell items.

• Each seller can sell items.

• Each item has a bidding start time, an end time, and an owner. Sellers are owners of

  their item. The start time and end time include the date as well.

• Each seller has a first name, last name, contact information, and credit card information. They also have a user name and a password.

• Contact information consists of an address, an email, and a telephone.

• An address consists of a street number and name, city, state, and zip code.

• Credit card information consists of owner name, card number, and expiration date.

• Each item has a name, condition, an initial price, a description, quantity, one or more pictures, and an owner.

• The condition could be New, Refurbished, or Explained. If the condition of an item is set to Explained, the seller should explain about the item condition in the item description.

• Each buyer has a first name and last name, contact information, and credit card information. They also have a user name and a password.

• When buyers’ login to Web site, they can go to the list of all available items and then go to the item detail page. Buyers can also search for an item. The application will search through item names for the search phrase.

• Buyers can bid on items. Once a bid is made, buyers are accountable for their bid. In other words, buyers cannot simply remove their bid. If they change their mind, all they can do is to update their bid with the price of zero. Of course, they can do that before the auction expires.

• After an auction expires, the buyer with the highest bid is the winner.

uppose you have a pre-existing class Dieter that models a person trying to monitor diet and weight to improve his/her Body Mass Index (BMI) rating. The class has the following data and behavior:

Make Dieter objects comparable to each other using the Comparable interface.

You are just writing a compreTo method for the class and not any other method.

Write the compareTo method for the class Dieter using the following criteria.

• Dieters are primarily compared by their BMI ratings;
• a dieter with a lower BMI is "less than" one with a higher BMI.
• If two dieters have the same BMI, the tie is broken by height; the shorter person is considered to be "less than" the taller one.
• If two dieters have the same BMI and height, the tie is broken by name. The dieter whose name comes first in alphabetical order is considered "less than" the one whose name comes later in ABC order.
• If the two dieters have the same BMI, height, and name, they are considered to be "equal." Your method should not modify any dieter's state. You may assume the parameter passed is not null
