Consumers spend an average of $21 per week in cash without being aware of where it goes (data extracted from ‘Snapshots: A Hole in Our Pockets,’ USA Today, January 18, 2010, p. 1A). Assume that the amount of cash spent without being aware of where it goes is normally distributed and that the standard deviation is $5.
(a) What is the probability that a randomly selected person will spend more than $25?
(b) What is the probability that a randomly selected person will spend between $10 and $20?
(c) Between what two values will the middle 95% of the amounts of cash spent fall?
The file Property Taxes contains the property taxes per capita for the 50 states and the District of Columbia. Decide whether the data appear to be approximately normally distributed.
Decide whether the data appear to be approximately normally distributed by:
(a) Constructing a box plot.
(b) Constructing a histogram.
(c) Comparing data characteristics to theoretical properties.
(d) Constructing a Quantile-Quantile Normal Probability Plot.
You must include all Excel results for this data as part of the justification for your conclusions. (Include them within the appropriate section – not at the end of your document.)
Your assignment must be submitted as a single word document via LMS. You will find the data in Property Taxes in LMS under Topic 5, Data Files.1 Based on Question 6.18 in Levine et al (2013)
