**Answer the following questions and be sure to
answer all parts and portions. **

1. In the following situation identify the ** implied
population** :

**A recent report on the weekly news presented the findings of a study on the effectiveness of Onglyza, along with diet and exercise, for treating diabetes.**

**The
implied population is**

2. In the following scenario identify the ** type
of statistical study** that was conducted:

**A Gallop poll surveyed 1,018 adults by telephone, and 22% of them reported that they smoked cigarettes within the past week.**

**The type of statistical study is**

3. In the following scenario what is the ** statistic **and the

**it would estimate:**

*parameter***A recent study of 460 drivers age 70 and over by the National Highway Traffic Safety Administration reported that 75% of those drivers had uncorrected vision problems.**

**The statistics is**

**The parameter is**

4.
What type of ** sampling procedure** was used to collect the data in the MM207
Student Data Set?

**The
specific sampling procedure that was used was**

5.
From the MM207 Student Data Set **identify**
one variable that is **discrete **and
one variable that **is continuous**. **Explain your reasoning. How do you know?**

a) The Discrete Variable is:

The reason the variable is discrete is because

b) The Continuous Variable is:

The reason the variable is continuous is because

6. From the MM207 Student Data Set identify the following:

a)
A variable measured at the **nominal **level of measurement is:

b)
A variable measured at the **ratio** level of measurement is:

c)
A variable measured at the **ordinal** level of measurement is:

7. What is the approximate percentage of students represented in the data set who are between the ages of 29 and 45 inclusive?

Place answer here.

8.
Assume that you are preparing a report on MM207 statistics students at Kaplan
University to present to the Kaplan Board of Trustees. Prepare an **appropriate graphical representation**
for **each **of the following variables.
Paste the graph here. Do this for (a) and for (b)

a) The different majors of students taking MM207.

Insert graph here

b) The number of hours spent on school work by students in MM207.

Insert graph here

9. Using the ** range rule of thumb,** estimate the standard deviation for the number
of credit hours students in this sample are taking and the shoe sizes of the
females in the class.

The estimate of the standard deviation for the number of credit hours students are taking is

The estimate of the standard deviation of the shoe size of the females in the class is

Then **using StatCrunch** compute the **actual standard deviation**.

The actual StatCrunch generated standard deviation for the number of credit hours students are taking is

The actual StatCrunch generated standard deviation of the shoe size of the females in the class is

**Compare the results. **

a)
Does the ** range rule of thumb** overestimate or
underestimate the standard deviation for number of credit hours?

Place response here

b)
Does the ** range rule of thumb** overestimate or
underestimate the standard deviation for shoe sizes of females?

Place response here

c)
How does the ** shape of the distribution**
impact what you conclude?

10.
Using measures of center (mean, median, and mode) and measures of variability (variance,
standard deviation, and range) compare the **number
of hours on school work** (Q11) and the **number
of hours watching television** (Q14) as required in the following questions:

a) Which variable has greater variability?

How do you know?

b)
What number of hours on school work would be
at the 10^{th} percentile?

c)
What number of hours watching television would
be at the 90^{th} percentile?
