The Hardcore Construction Company has two offices, one in Atlanta and one in New Orleans. Fifteen engineers work in the Atlanta office, and fourteen engineers work in the New Orleans office. The business manager decided to use a 2-sample t-test to compare the mean salaries of engineers in the two offices. Because the populations were so small he used the salaries of all the employees at both companies in the computation. Is the 2 sample t-test an appropriate inferential technique in this situation?

Transcribed Image Text:The Hardcore Construction Company has two offices, one in Atlanta
and one in New Orleans. Fifteen engineers work in the Atlanta office,
and fourteen engineers work in the New Orleans office. The business
manager decided to use a 2-sample t-test to compare the mean salaries
of engineers in the two offices. Because the populations were so small
he used the salaries of all the employees at both companies in the
computation. Is the 2 sample t-test an appropriate inferential technique
in this situation?
O No, because the entire population information was used from both offices.
Because no samples were taken, a t-test should not be used.
O Yes, because Atlanta and New Orleans are about 500 miles apart so the two
groups of engineers can be assumed to be independent.
O No, because the number of engineers in the two offices are different
O Yes. Both Atlanta and New Orleans are large cities, so the salaries are
comparable.
O Yes, because he is comparing the means of two small groups
