Approximate the percent increase in waist size that occurs when a 130 lb person gains 30.0 lbs of fat. assume that the volume of the person can be modeled by a cylinder that is 4.0 feet tall. the average density of a human is about 1.0 g/cm3 and the density of fat is 0.918 g/cm3

What type of solution is formed if 10 g of kclo3 are dissolved in 100g of water at 30

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
