Is there a difference in the amount of airborne bacteria between carpeted and uncarpeted rooms? In an experiment, 5 rooms were carpeted and 5 were left uncarpeted. The rooms are similar in size and function. After a suitable period of time, the concentration of bacteria in the air was measured (in units of bacteria per cubic foot) in all of these rooms. The data and summaries are provided:

x-bar s
Carpeted Rooms 184 27.0
Uncarpeted Rooms 173 17.9
6.
What is the value of the two-sample t statistic for this test, rounded to four decimal places?
