If two tablespoonfuls of a 10% w/v povidone–iodine solution were diluted to 1 quartwith purified water, what would be the ratio strength of the dilution?
A patient's glucose result is outside of the range of the analyzer, so the sample has to be diluted. 50 microliters of serum is added to 100 microliters of diluent and the diluted sample is re-analyzed. The glucose value of the diluted sample is 80 mg/dL. What is the glucose value in the original sample?
Penicillin is produced by the Penicillium fungus, which is grown in a broth whose sugar content must be carefully controlled. Several samples of broth were taken on three successive days, and the amount of dissolved sugars, in milligrams per milliliter, was measured on each sample. The results were as follows.

He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here's the data: Air (ft') Water (ft) 0.52 0.44 0.58 0.41 0.50 0.55 0.46 0.61 0.38 0.45 Does the data give convincing evidence air filled balloons can attain a greater volume than water filled balloons?arrow_forward& Find t2.dr for the following combinations of a and n. a. a = 0.05, n = 15 b. a=0.01, n=20 a = 0.10, n= 8 %3D с.arrow_forward
- An engineer was interested in the effect of two factors on strength of sheet castings of a polymer. One factor was time in a polymerization bath with 1% catalyst. The other factor was the temperature of the polymerization bath. The engineer tried two times (20 minutes and 60 minutes) and two temperatures (100 and 120 degrees F). He treated samples of polymer under each of the four sets of conditions. Then he measured flexural strength (in pounds per square inch, or psi) on samples of sheet castings of the polymer. The results are shown in the table below: 100 degrees 20 minutes 9500 10650 9700 9950 10100 60 minutes 11500 11650 11250 11250 11900 120 degrees 11300 11750 11600 11650 11700 10900 11500 11850 11700 11650 Test for main factor effects or factor interactions, at the 5% significance level.arrow_forwardA patient has 1 liter of 0.9% NS ordered.
