Problem 1: USE CALCULATOR/FORMULA ONLY. (2 points)
In Applied Life Data Analysis (Wiley, 1982), Wayne Nelson presents the breakdown time of an
insulating fluid between electrodes at 34 kV. The times, in minutes, are as follows: 0.19, 0.78,
0.96, 1.31, 2.78, 3.16, 4.15, 4.67, 4.85, 6.50, 7.35, 8.01, 8.27, 12.06, 31.75, 32.52, 33.91, 36.71,
and 72.89. Complete the following table:
Mean
Median
Mode
Standard Deviation
Problem 2: USE CALCULATOR/FORMULA ONLY. (2 points)
There are four gorillas in the LA zoo, ages 7, 10, 15 and 21. The mean and standard deviation of
the age of the gorillas at the LA zoo are
Mean
Standard Deviation
ISE 130 – Fall 2018
Problems 3 to 6: Use Minitab for the following problems. Data for the following problems are
provided in an Excel spreadsheet online.
Problem 3 (3 points)
An article in the Journal of Physiology [“Response of Rat Muscle to Acute Resistance Exercise
Defined by Transcriptional and Translational Profiling” (2002, Vol. 545, pp. 27–41)] studied gene
expression as a function of resistance exercise. Expression data (measures of gene activity) from
one gene are shown in the following table. One group of rats was exercised for six hours while
the other received no exercise.
a) Compute the sample mean and standard deviation of the exercise and no-exercise groups
separately.
b) Construct a dot diagram for the exercise and no-exercise groups separately. Comment on any
differences for the groups. (Data provided in spreadsheet)
Problem 4
The net energy consumption (in billions of kilowatthours) for countries in Asia in 2003 was as
recorded (source: U.S. Department of Energy Web site, www.eia.doe.gov/emeu). (data in
spreadsheet)
a) Construct a stem-and-leaf diagram for these data and comment on any important
features that you notice. (1 point)
b) What conclusions can you draw from your plots in parts a and b? (1 point)
Problem 5:
In the 2000 Sydney Olympics, a special program initiated by IOC president Juan Antonio
Samaranch allowed developing countries to send athletes to the Olympics without the usual
qualifying procedure. The spreadsheet provides the 71 times for the first round of the 100 meter
men’s swim (in seconds).
a) Use Minitab to complete the following table (2 points)
Mean
Median
Variance
Standard
Deviation
Range
b) Construct a box plot of the data. Are there outliers in the data? If so, explain. (1 point)
c) If there are outliers in the original data, repeat (a) and (b) for the data without the
extreme outlier and comment. (2 points)
d) Compare the distribution of the data with and without the extreme outlier. (1 point)
e) Construct a normal probability plot of the data. Are the data normally distributed?
Explain. (1 point)

Problem 6
An important quality characteristic of water is the concentration of suspended solid material.
Following are 60 measurements on suspended solids from a certain lake. Construct a stem-andleaf diagram for these data and comment on any important features that you notice.
a) Provide a summary table (descriptive statistics) of the data in the spreadsheet. (1 point)
b) Construct the following plots: (2 point)
i) Stem and leaf plot
ii) Histogram
iii) Box plot
iv) Normal distribution plot
c) What conclusions do you draw from the above plot? (1 point)
