Purpose: Collect data
Estimate the proportion of parking spaces that are empty, used illegally,
or used poorly
Estimate the proportion of NC cars that have late inspection stickers and
the average number of months late
Data Collection:
Check each of your randomly selected (non-handicapped)
parking spaces in the Forsyth lot
for the following information:
"Empty" column Make a check in the "Empty"
column if a space is empty. If the space is
empty move to your next space (row on your data sheet) and continue.
"Illegal" column Make a check for
illegal parking on the "space" row for an incorrectly
parked car. Cars with no sticker or a sticker that is _____________
would be illegally parked in Forsyth lot, unless there is a handicapped
placard visible or a permission sticker from the clinic. Cars with
a visitor
sticker on the dash or a sticker that is purple are legally parked. If
you
find something else, please make a note and bring it back for discussion.
"Poor" column Check the "Poor" column if a car parked over the line for its space.
"NC" column
Check the "NC" if the car is from NC--determined by its license plate.
The next two columns of data only apply to NC cars. Leave other cells
blank.
"Late" column Make a check
in the "Late" column for a NC car whose inspection
sticker has expired. If the car is not a NC car, leave the "# Months
Late"
column blank and proceed to the next space on your list.
"# Months Late" column Determine
the number of months that the inspection sticker is late.
If sticker is not late, the "# Months Late" value is 0. If
sticker is for
March, month 3, and if it is June today, month 6, then the sticker
is 3 months late.
At the bottom of each column record the n value for
the sample of data that you have collected
for a particular question. For the "Empty,
" "Illegal," and "Poor," columns, n=30, because you
must check each of your 30 spaces. The population
will be spaces available in the Forsyth
lot. For the "Late" and "# Months Late" columns,
n will be the number of parked NC cars for
which you determine a "# Months Late" value.
Return to class after you collect your data for computations and bonus credit.
