9.51 Death row and the single-sample t test: The
Florida Department of Corrections publishes an online
death row fact shcet. It reports the average time on
death row prior to execution as 11.72 ycars but pro-
vides no standard deviation. This mcan is a parameter
because it is calculated from the entire population of
exccuted prisoners in Florida. Did the time spent on
death row change over timc? According to the execu-
tion list linked to the same Web site, the six prison-
crs executed in Florida during the years 2003, 2004,
and 2005 spent 25.62, 13.09, 8.74, 17.63, 2.80, and
4.42 years on death row, respectively. (All were men,
although Aileen Wuornos, the serial killer portrayed by
Charlize Theron in the 2003 film Monster, was among
the three prisoners executed by the state of Florida in
2002; Wuornos spent 10.69 years on death row.)
a. Using symbolic notation and formulas (where
appropriate), determine the appropriate mean and
standard error for the distribution of means. Show
all steps of your calculations.
b. Using symbolic notation and the formula, calculate
the t statistic for time spent on death row for the
sample of executed prisoners.
c. The execution list provides data on all prisoners
executed since the death penalty was reinstated in
Florida in 1976, Included for each prisoner are the
name, race, gender, date of birth, date of offense,
date sentenced, date arrived on death row, data of
execution, number of warrants, and years on death
row. State at least one hypothesis, other than year of
execution, which could be examined using ar dis-
tribution and the comparison mean of 11.72 years
on death row. Be specific about your hypothesis
(and if you are interested, you can search for the
data online).
d. What additional information would you need to
calculate a z score for the length of time Aileen
Wuornos spent on death row?
Write hypotheses to address the question "Did the
time spent on death row change over time:
C.
f Using these data as "over time and the mean of
