Minitab Assignment on Ch 20

 


 

Summer II Distance 2016

 


 

A meteorologist claims that the average highest temperature in cities in the United States is 37 degrees Celsius.

 

A random sample of 51 cities in the United Sates is selected, and the highest temperatures are recorded for each

 

city. In this assignment you will use Minitab to implement the t-procedures for inference for the mean to see if

 

the average highest temperature for cities in the United States really is 37 degrees. The data is available as a

 

Minitab data file on your course Moodle site.

 

Rather than doing any analyses by hand, the goal is to let Minitab do all of the required calculations; details for

 

the necessary Minitab commands are given below. After obtaining your Minitab output, you will answer the

 

attached questions in the space provided.

 

Following the steps below, you will get Minitab to find a confidence interval for the mean temperature in the

 

United States. You will also conduct a hypothesis test to see if the average temperature really is 37 degrees.

 

Obtaining the Minitab output: It is assumed that you have experience with Minitab from Math 2208, but if

 

you are brand new to it, or need to review, it is recommended that, for practice, you can work though the

 

Minitab guide found on your lab Moodle site.

 

If you have a PC at home or are using a PC on campus, use the instructions for Minitab Version 17.

 

If you are using a Mac, use the instructions for Minitab Express. Do not use both sets of instructions.

 

INSTRUCTONS IF USING MINITAB VERSION 17

 

1. Open the Minitab data file TEMP.MTW from your M2209 class Moodle page.

 

2. Type your name and student ID in the Session window.

 

3. Run a t-test using Stat > Basic Statistics > 1-Sample t... Leave the drop down menu at the default ?one or

 

more samples, each in a column? and click in the box, directly below that. When the label appears, double

 

click on C1 Temp on the left. In addition, check the box ?Perform hypothesis test? and type the Ho value

 

in the space ?Hypothesized mean:?. Click OK. The results for the test will then appear in the session

 

window.

 

4. Also obtain a 99% confidence interval for the mean using Stat > Basic Statistics > 1-Sample t... The

 

column should still be in place in the dialogue window. Uncheck the ?Perform hypothesis test? box. Click

 

on the Options... button, and in the new dialogue window that opens change the ?Confidence level? to 99.0.

 

Click OK in both windows. The results for the CI (among other things) will appear in the session window.

 

Print a copy of the Session window.

 

5.

 


 

Obtain a histogram using Graph > Histogram click on Simple and then in the dialogue window again

 

enter the column number in the ?Graph variables:? space, and click OK. Results appear in a separate

 

window.

 

Print a copy of the graph.

 

Step #6 is on the following page.

 


 

*Data collected from The World Almanac Book of Facts

 


 

6. Close Minitab with File > Exit.

 

Analysis: Answer the questions in the space provided on the last page. Remember that all statements

 

must be worded in the context of the problem. Also, do not perform any calculations - simply highlight or

 

circle the appropriate parts of the Minitab output as needed.

 

Submit: Minitab output, graph and your answers sheet. WRITE NEATLY AND STAPLE PAGES!

 

MINITAB EXPRESS INSTRUCTIONS

 

1. Open the Minitab data file TEMP.MTW from your M2209 class Moodle page.

 

2. Run a t-test using Statistics > One Sample > t... Click in the box beside ?Sample?. When the label appears,

 

double click on C1 Temp on the left. Check the box ?Perform hypothesis test? and type the Ho value in the

 

space ?Hypothesized mean:?. Click OK. The results for the test will then appear in the output window.

 

Click on the output then select File > Print to print the output.

 

3. Obtain a 99% confidence interval for the mean using Statistics > One Sample > t... . Leave the drop down

 

menu at the default ?Sample data in a column? and click in the box beside ?Sample?. When the label

 

appears, double click on C1 Temp on the left. Click on the ?Options? tab and change the ?Confidence

 

Level? to 99.0. Click OK. The results for the CI (among other things) will appear in the output window.

 

Click on the output then select File > Print to print the output.

 

4. Obtain a histogram using Graphs > Histogram > Simple under Single Y Variable; double click on C1

 

Weight to get this to appear in the ?Y variable:? space, and click OK. Results appear in the output window.

 

Click on the graph then select File > Print to print the graph.

 

5. In the Minitab spreadsheet, go to Column C2 and row 1. This means you?ll be right beside the 36 which is

 

the first value in the Temp column C1. Type Math2209 in this spot.

 

Express on PC: Next choose Data > To Text. Enter C2 in the box Recode values in the following

 

columns.

 

Express on Mac: Choose Data > Recode > To Text. Double-click on C2 to its value appears in values in

 

the following columns.

 

Under the box Recoded value replace Math2209 with your name and student number. Then hit OK. The

 

output will appear in the Output window. Select File > Print to print this output.

 

6. Close Minitab with File > Exit.

 

Analysis: Answer the questions in the space provided on the last page. Remember that all statements

 

must be worded in the context of the problem. Also, do not perform any calculations - simply highlight or

 

circle the appropriate parts of the Minitab output as needed.

 

Submit: Minitab output, graph and your answers sheet. WRITE NEATLY AND STAPLE PAGES!
