Chapter 4, Problem 1EA
Although experiments typically manipulate some aspect of the environment to create different treatment conditions, it is also possible to manipulate characteristics of the participants. For example, researchers can give some participants a feeling of success and others a feeling of failure by giving false feedback about their performance or by rigging a task to make it easy or impossible (Thompson, Webber, &c Montgomery, 2002). By manipulating the participants’ experiences, it is possible to examine how people’s performance and attitudes are influenced by success and failure.
Other research has manipulated the participants’ mood. Showing movies, playing music, or having participants read a series of positive (or negative) statements can induce different mood states (positive, negative, neutral). Being able to manipulate mood in the laboratory allows researchers to study how mood influences behaviors such as memory (Teasdale Be Fogarty, 1979) or the ability to read emotions in facial expression (Bouhuys, Bloem, &c Groothuis, 1995), and how other factors, such as alcohol consumption, affect mood (Van Tilburgh & Vingerhoets, 2002).
Suppose you are planning a research study in which you intend to manipulate the participants’ mood; that is, you plan to create a group of happy people and a group of sad people. For example, one group will spend the first 10 minutes of the experiment listening to upbeat, happy music, and the other group will listen to funeral dirges.
- (L0 2) Do you consider the manipula- tion of people’s moods to be an ethical violation of the principle of no harm? Explain why or why not.

Elementary StatisticsBase on the same given data uploaded in module 4, will you conclude that the number of bathroom of houses is a significant factor for house sellprice? I your answer is affirmative, you need to explain how the number of bathroom influences the house price, using a post hoc procedure. (Please treat number of bathrooms as a categorical variable in this analysis)Base on the same given data, conduct an analysis for the variable sellprice to see if sale price is influenced by living area. Summarize your finding including all regular steps (learned in this module) for your method. Also, will you conclude that larger house corresponding to higher price (justify)?Each question need to include a spss or sas output.
Instructions:
You have to use SAS or SPSS to perform appropriate procedure: ANOVA or Regression based on the project data (provided in the module 4) and research question in the project file. Attach the computer output of all key steps (number) quoted in…
Elementary StatsBase on the given data uploaded in module 4, change the variable sale price into two categories: abovethe mean price or not; and change the living area into two categories: above the median living area ornot ( your two group should have close number of houses in each group). Using the resulting variables,will you conclude that larger house corresponding to higher price?Note: Need computer output, Ho and Ha, P and decision. If p is small, you need to explain what type ofdependency (association) we have using an appropriate pair of percentages.
Please include how to use the data in SPSS and interpretation of data.
An environmental research team is studying the daily rainfall (in millimeters) in a region over 100 days.
The data is grouped into the following histogram bins:
Rainfall Range (mm) Frequency
0-9.9
15
10 19.9
25
20-29.9
30
30-39.9
20
||40-49.9

a) If a random day is selected, what is the probability that the rainfall was at least 20 mm but less than 40
mm?
b) Estimate the mean daily rainfall, assuming the rainfall in each bin is uniformly distributed and the
midpoint of each bin represents the average rainfall for that range.
c) Construct the cumulative frequency distribution and determine the rainfall level below which 75% of the
days fall.
d) Calculate the estimated variance and standard deviation of the daily rainfall based on the histogram data.

They wish to fairly divide the cake using the lone chooser method. Pam likes strawberry twice as much as chocolate or vanilla. Rob only likes chocolate. Sam, the chooser, likes vanilla and strawberry twice as much as chocolate. In the first division, Pam cuts the strawberry piece off and lets Rob choose his favorite piece. Based on that, Rob chooses the chocolate and vanilla parts.
