Listed below are amounts of court income and salaries paid to
the town justices. All amounts are in thousands of dollars.
Construct a scatterplot, find the value of the linear correlation
coefficient r, and find the P-value using alpha equals0.05 . Is
there sufficient evidence to conclude that there is a linear
correlation between court incomes and justice salaries? Based on
the results, does it appear that justices might profit by levying
larger fines? Court Income 64.0 405.0 1567.0 1132.0...

The file P17_05.xlsx contains data on 100 consumers who drink
beer. Some of them prefer light beer, and others prefer regular
beer. A major beer producer believes that the following variables
might be useful in discriminating between these two groups: gender,
marital status, annual income level, and age. b. Consider a new
customer: male, married, income $42,000, age 47. Use the logistic
regression equation to estimate the probability that this customer
prefers Regular. How would you classify this person?

This dataset contains consumer responses indicating the number
of times they had to send their product for repair and their
satisfaction with the repair process. Create a graph which can be
used to visually demonstrate the relationship between the two
columns of data. Ensure that the chart is professional with
appropriate titles, axis labels, etc. Note any observations you see
in your visualization (type these as sentences directly into an

Conductivity is one of many properties measured to evaluate
water quality. The table below (also attached as an Excel file)
contains conductivity measurements (µS/cm) of groundwater samples
from a single well.
First, prepare a graph of the raw data.
Then set up estimates of the conductivity
population average (95% CI),
population standard deviation (95% CI), and
a future individual measurement (95% PI).
Also develop a 95% tolerance interval estimate of the
conductivity that will include 99% of the conductivities.

You are currently working at NCLEX Memorial Hospital in the
Infectious Diseases Unit. Over the past few days, you have noticed
an increase in patients admitted with a particular infectious
disease. You believe that the ages of these patients play a
critical role in the method used to treat the patients. You decide
to speak to your manager, and together you work to use statistical
analysis to look more closely at the ages of these patients.

A study of reading comprehension in children compared three
methods of instruction. The three methods of instruction are called
Basal, DRTA, and Strategies. Basal is the traditional method of
teaching, while DRTA and Strategies are two innovative methods
based on similar theoretical considerations. The READING data set
includes three response variables that the new methods were
designed to improve. Analyze these variables using ANOVA methods.
Be sure to include multiple comparisons or contrasts as needed.
