5. Suppose a rehabilitation psychologist has developed a new job
skills training program for people who have not been able to hold a
job. Of the 14 people who agree to be in the study, the researcher
randomly picks seven of these volunteers to be in a experimental
group who will go through the special training program. The other
seven volunteers are put in a control group who will go through an
ordinary job skills training program. After finishing the...

A psychologist developed a survey to measure people’s feelings
toward online dating. Sixty randomly selected subjects were given
the survey, which showed a sample mean of 8.2 and a sample standard
deviation of 1.6.
Construct the 95% confidence interval for the population mean.
Show work.
If the scale of results is from 1(very negative feelings) to 10
(very positive feelings), what can you say about this population
based on your confidence interval?
