Media Preference (Version 1)For this discussion, you will use VoiceThread technology. Under the Introduction and Resources area there is a link to VoiceThread that includes videos on how to use this technology. For this discussion, first find or create a data set. Then, create a graph from those data. Your post should be a VoiceThread that explains how you created the graph and why you selected the graph that you did. In your responses to other students, discuss the type of data as well as what ..

Homework Problems: Questions: 1-8Question 1:Suppose you are given a data set that classifies each sample unit into one of four categories: A, B, C, or D. You plan to create a computer database consisting of these data, and you decide to code the data as A=1, B=2, C=3, and D=4. Are the data consisting of the classifications A, B, C, and D qualitative or quantitative? After the data are input as 1, 2, 3, or 4, are they qualitative or quantitative?A. Quantitative, because they can only be classifie..
Questions: 1-20Q1.Suppose you're given a data set that classifies each sample
unit into one of four categories: A, B, C, D. You plan to create a computer
database consisting of these data, and you decide to code the data as A = 1, B
= 2, C = 3, and D = 4. Are the data consisting of classification A, B, C, and D qualitative
and quantitative? After the data are input as 1, 2, 3 or 4, are they
qualitative or quantitative? Q2.A company tracked all credit card purchases during the year
2005 and ..
Part A: Exploratory Data Analysis
Open the files for the course
project and the data set.· For each of the five variables,
process, organize, present and summarize the data. Analyze each variable by
itself using graphical and numerical techniques of summarization. Use Excel as
much as possible, explaining what the results reveal. Some of the following
graphs may be helpful: stem-leaf diagram, frequency/relative frequency t..
Homework Problems: Questions: 1 (a to d)
primary care doctors feel overworked and burdened by potential lawsuits. In
fact, a group of researchers reported that 64% of all general practice
physicians do not recommend medicine as a career. Let x represent the number of
sampled general practice physicians who do not recommend medicine as a
career. Complete parts a through d.
a. Explain why x is approximately a binomial
b. Use the researchers' ..
Questions: 1-8Q1.A finance journal published a study of whether the decision to invest in the stock market is dependent on IQ. Information on a sample of 153,401 adults living in Finland formed the database for the study. An IQ score (from a low score of 1 to a high score of 9) was determined for each Finnish citizen as well as whether or not the citizen invested in the stock market. The following table gives the number of Finnish citizens in each IQ score/investment category. ..

The Organization Development Journal (Summer 2006) reported
on the results of a survey of human resource officers (HROs) at major employers
located in a southeastern city. The focus of the study was employee behavior,
namely absenteeism, promptness to work, and turnover. The study found that 55%
of the HROs had problems with employee absenteeism; also 41% had problems with
turnover. Suppose that 22% of the HROs had problems with both absenteeism and
Questions: 1-9Q1.The ages of a group of 50 women are approximately normally
distributed with a mean of 47 years and a standard deviation of 6 years. One
woman is randomly selected from the group, and her age is observed.a. Find the probability that her age will fall
between 53 and 62 years.b. Find the probability that her age will fall
between 46 and 54 years.c. Find the probability that her age will be
less than 32 years.d. Find the probability that her age will
A random sample of 89 observations produced a mean x = 25.7
and a standard deviation s=2.5.
a. Find a 95% confidence interval
b. Find a 90% confidence interval
c. Find a 99% confidence interval
A company wants to test a randomly selected
sample of n water specimens and estimate the mean daily rate of pollution
produced by a mining operation. If the company wants a 95% confidence interval

Questions: 1-13Q1.A professor at a local
university conducted a survey of 135 businesses in a city to determine what
motivates small businesses to export their products. The CEOs were asked to
respond to the statement? "Management believes that the business can
achieve economies of scale by? exporting" on a scale of 1? (strongly
disagree) to 5? (strongly agree). Summary statistics for the n=135 scale scores
were reported as x=3.83 and s=1.4 In his? study, the professor hypothesized
that if the t..
Part B: Hypothesis Testing and Confidence IntervalsComplete the following four hypotheses,
using ? = 0.05 for each.1. Mean sales per week exceeds 41.5 per salesperson2. Proportion receiving online training is less than 55%3. Mean calls made among those with no training is less than 1454. Mean time per call is greater than 15 minutes
1) Using the same data set from part A, perform the hypothesis test for
each speculation in order to see if ..
Part C: Regression and Correlation Analysis
Use the dependent variable (labeled Y) and
one of the independent variables (labeled X1, X2, and X3) in the data file.
Select and use one independent variable throughout this analysis. Use Excel to
perform the regression and correlation analysis to answer the following.1. Generate a scatterplot for the specified dependent variable (Y) and
the selected independent variable (X), including the graph of the "best
fit" line. Interpret.2. Determ..
Questions: 1-5Q1.Suppose you fit the first-order multiple regression model Y
= B0 + B1X1 + B2X2 + e to n = 25 data points and obtain the
prediction equation Y = 50.11 + 5.44X1 + 1.33X2. The
estimated standard deviations of the sampling distributions of B1 and B2 are 0.98
