Data: Click on “StatCrunch” on MyLab
Statistics, then “Data sets from the
textbook”. Scroll down to Chapter 7, then
click on Chapter 7: Case Study: Human
Body Temperature: What’s Normal?
Do all of the work below with the “Men” data
set.
• Use a statistical software package to
complete the analysis of Exploratory
Data Analysis and Inferential Statistics.
You are strongly encouraged to use
StatCrunch (in MyLab Statistics). You may
also use any other software packages (s.a.
MINITAB, or SPSS). However, if you use
other software, you are on your own, for
your instructor will only help with question
with regards to StatCrunch.
A) Exploratory Data Analysis
1. Construct a stem and leaf display.
2. Construct a histogram.

MTH 245: Project 1A
Purpose:
This project is to help you apply concepts to real
world, real data analysis. In the real world
computers do most of the hard work for
statisticians. This project will help you
understand how an informative decision is made
using data analysis. After completing this
project, you should be able to determine which
statistical procedures are appropriate; and use
StatCrunch to carry out the procedures and
interpret the output.
Directions:
• In an article in the Journal of Statistics
Education (vol., no 2), Allen Shoemaker
describes a study that was reported in the
Journal of American Medical Association
(JAMA). It is generally accepted that the
mean temperature of an adult human is
98.6°F. In his article, Shoemaker uses the
data from the JAMA article to test his
hypothesis. The data for the JAMA article
were collected from healthy men and

A) Exploratory Data Analysis

(Spring 2022) MTH 245 (E82N) – Statistics I
1. Construct a stem and leaf display.
2. Construct a histogram.
3. Construct a boxplot and use it to
investigate the data for outliers.
4. Obtain the sample mean, median, mode,
and standard deviation.
B) Inferential Statistics
1. Construct a normal probability plot or
quantile-quantile (QQ) plot to assess
normality. Use this assessment to
determine which tests are appropriate for
these data for confidence interval and test
of hypothesis as you will use these
procedures for parts 2 and 3 below.
2. Construct a 99% confidence interval for μ,
for mean body temperature for all adult
males in the population.
3. At the 1% significance level, do the data
provide sufficient evidence to conclude
that the mean body temperature of men is
98.6°F?
4. Using the software output, perform the
confidence interval and the full hypothesis
test.
