Concept explainers

Computing Algorithms

A computing algorithm is a set of instructions or a process for solving computational problems. In other words, it contains a set of rules that indicate the step-wise process to solve a problem. The algorithm takes a set of inputs, executes the instructions given to it, and produces the desired output.

19. Age of Death-Row Inmates In 2002, the mean age of an in-
mate on death row was 40.7 years, according to data obtained
from the U.S. Department of Justice. A sociologist wondered
whether the mean age of a death-row inmate has changed since
then. She randomly selects 32 death-row inmates and finds
that their mean age is 38.9, with a standard deviation of 9.6.
Construct a 95% confidence interval about the mean age.
What does the interval imply?
Answers: Fail to Reject Ho: t(critical) = -2.0395, t-value = -1.06. CI = 42.36 - 35.44
