Question

The three data sets presented below have the same MEAN and RANGE. Assume that these data were obtained from samples.

Data Set A: 5, 7, 9, 11, 13, 15, 17.

Data Set B: 5, 6, 7, 11, 15, 16, 17.

Data Set C: 5, 5, 5, 11, 17, 17, 17.

What sample parameter will you use to differentiate among them? Support your answer by computing the value of this parameter for each of these sample data sets.

Answer #1

The Money Pit Mortgage Company is interested in monitoring the
performance of the mortgage process. Fifteen samples of five
completed mortgage transactions each were taken during a period
when the process was believed to be in control. The times to
complete the transactions were measured. The means and ranges of
the mortgage process transaction times, measured in days, are as
follows:

The following 2 parts relate to this scenario and data. (Data
listed below)
1. Consider the two separate samples given in
the data set (samplecomparison.xlsx). Answer the questions
below.
The range of the first data set is _____ .
The variance of the first data set is _____ . (Round to three
decimal places as needed)
The standard deviation of the first data set is _____ . (Round
to three decimal places as needed)
The range of the second data...

Data Set A: 11, 12, 13
Data Set B: 9, 10, 11, 12, 13, 14, 15
Data Set C: 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18
Find the mean, sample standard deviation–treating the data as a
sample, and the population standard deviation–treating the data as
a population.
