EBTM 350 MYLAB PROBLEMS EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
Compute the Euclidean distance between the sets of points below.
a. (2,4) and (9,3)
b. (11,−3,31) and (19,14,−52)
CH 10
Q1
For the three clusters identified in the accompanying Distance Matrix After
Second Clustering table, find the average and standard deviations of each
numerical variable for the schools in each cluster and compare them with the
average and standard deviation for the entire data set. Does the clustering show
distinct differences among these clusters?
CH 10
Q2
Using only Credit Score, Years of Credit History, Revolving Balance, and
Revolving Utilization, apply single linkage cluster analysis to the first six records
in the accompanying Credit Approval Decisions data and draw a dendogram
illustrating the clustering process.
CH 10
Q3
, Use the given data to classify the record below using the k-NN algorithm for k=1
to 5.
Loan Purpose- EDUCATION
Checking- 680
Savings- 600
Months Customer - 50
Months Employed- 18
CH 10
Q4
The accompanying Myatt Steak House data provides five years of data on key
business results for a restaurant. Identify the leading and lagging measures, find
the correlation matrix, and propose a cause-and-effect model using the strongest
correlations.
CH 10
Q5
Suppose that a small candy store makes Valentine's Day gift boxes that cost
$15.00 and sell for $17.00.In the past, at least 30
boxes have been sold by Valentine's Day, but the actual amount is uncertain; the
owner has often run short or made too many. After the holiday, any unsold boxes
are discounted 50%and are eventually sold. Assume a demand of 45 and a
quantity made of
48.
Construct an influence diagram for profit.
