uncarne dirrerent from the mean amount of airborne bacteria in uncarpeted rooms. To test this, carpeted and Carpeted rooms 12.1 Uncarpeted rooms 9.8 Sample mean of bacteria per ft' Sample std. dev. of bacteria per ft' Number of rooms tested 3.2 2.7 20 23 TO .05 to see test if the amount off airborne bacteria is different in carpeted rooms than in uncarpeted rooms. I. State your hypotheses I. State the allowable type I error rate (a) III. Calculate your test statistic, the p-value and draw the physical representation of the p-value IV. Make your decision to either reject the null or fail to reject the null. V. Make a concluding statement.
