The reduction of the amount of medication in the body can be modeled by the equation A = A0ekt, where A is the amount at time t, A0is the amount at t = 0, and k is the decay constant (k <0 ). The half-life time of a certain medication is 3.5 h. A person takes 400 mg of the medication at 10, and then additional 400 mg every 4 h. Determine the amount of the medication in a patient’s body 23 h after taking the first dose.|
After determining the value of k. define a

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
A recent survey of 400 americans asked whether or not parents do too much for their young adult children.
