Transcribed Image Text:12. Critical Thinking Consider the following types of data that were obtained
from a random sample of 49 credit card accounts. Identify all the averages
(mean, median, or mode) that can be used to summarize the data.
(a) Outstanding balance on each account
(b) Name of credit card (e.g., MasterCard, Visa, American Express, etc.)
(c) Dollar amount due on next payment
13. Critical Thinking Consider the numbers
2 3 4 5 5
(a) Compute the mode, median, and mean.
(b) If the numbers represent codes for the colors of T-shirts ordered from a
catalog, which average(s) would make sense?
(c) If the numbers represent one-way mileages for trails to different lakes,
which average(s) would make sense?
(d) Suppose the numbers represent survey responses from 1 to 5, with
1 = disagree strongly, 2 = disagree, 3 = agree, 4= agree strongly,
and 5= agree very strongly. Which averages make sense?
14. Critical Thinking Consider two data sets.
Set A: n = 5; x = 10
Set B: n = 50; x = 10
(a) Suppose the number 20 is included as an additional data value in Set A.
Compute for the new data set. Hint: Ex= nx. To computex for the new
data set, add 20 to Ex of the original data set and divide by 6.
