PCLAB #2

(1) Start MINITAB as before. Remember to enable the command language.
Also launch WORD or WORDPERFECT  so that you can paste any  results you want printed to this page.
(2) The following data set has 7 columns. It has data on 31 men in an exercise study.
Put this data into MINITAB using the copy-paste method. Select the 31 rows by dragging across them and copy them.
Go to MINITAB and click in the row1, column1 cell of the spreadsheet. Then use EDIT -> PASTE CELLS. You should
see the data inserted. Name the columns in the top spaces.
(3) Do a regression study for y = “oxygen” vs x = “time” . Include the plot of the data, descriptive stats, the correlation
and the regression equation. Print out these results.
(4) Do a regression study for y = “oxygen” vs x = “pulse” . Include the plot of the data, descriptive stats, the correlation
and the regression equation. Print out these results.

v1 = oxygen consumption in vol/body wt/unit time
v2 = age in years
v3 = weight in kilograms
v4 = time to run 1.5 miles
v5 = resting pulse rate
v6 = pulse rate at end of run
v7 = max pulse rate during run

(5) Let's do a simulation study: Consider a box of 5 numbers    [0 0 0 0 1]    with p = .20 for
the proportion of 1's in the box. Note the average of the numbers in the box is also .20 .
If we draw 50 times from the box, let X be the number of 1's drawn. X is also the sum of
the 50 numbers drawn. X is random and we can't say what it will be exactly before the
drawing takes place. To empirically examine what the sum X may be we will repeat the 50 draws
500 times getting an X value each time and explore the results. We will let the computer do
all this work for us to save a lot of time. This process is called a simulation study. To simulate this
drawing use the session commands:
Random 500 C1 ;                    (Note it ends in a semicolon)
binomial 50 .2 .                     (Note it ends in a period)
The column C1 (name it SUM) should contain 500 numbers, the result on the SUM  X repeated 500 times.
Paste the following results to a WORD page and print from there.
***Get descriptive stats on C1.
***Do a histogram on C1 (you may want to tinker with the cutpoints that set
the intervals - find such an option in the histogram menu and try making your own cutpoints.)
***Consider our theory - what is the EV and SE for the SUM X of this example?
