An experiment is set up to study the weights of 35 mice after they are injected with a drug. the population mean is 23.50 grams with a standard deviation of 3.40 grams. the standard error of he sample is (round off your answer to the nearest hundredth.)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
