Question

Is there a difference in the amount of airborne bacteria between carpeted and uncarpeted rooms? In an experiment, 7 rooms were carpeted and 7 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: Find a 95% confidence interval for the difference in mean bacterial concentration in the air of carpeted rooms versus uncarpeted rooms (use the conservative value for the degrees of freedom) The researcher wants to investigate whether carpet makes a difference (either increases or decreases) in the mean bacterial concentration in air. Compute the two-sample t statistic for this test. Find the P-value for the test (use the conservative value for the degrees of freedom).
