What does the P value mean? - ️️P is the probability that the differences between the groups are due to chance If P is smaller than 5% (0.05), the null hypothesis is rejected = low probability that the differences are due to chance If P is larger than 5% then we fail to reject the null = greater probability that the differences are due to chance T-test - ️️compares two groups and determines if they are statistically different from each other Pipette over delivery - ️️pushin...

The physician orders a 35% aerosol mask to be set up for a patient who requires an inspiratory flow of 42 L/min. What is the minimum flow rate to which the flowmeter must be set to meet this patient's in- spiratory flow demands? A. 6 L/min B. 8 L/min C. 10 L/min D. 12 L/min - ANSWER B, The air/O2ratio for a 35% oxygen mixture is 5 : 1.
