You're doing an experiment to test whether students fed a new element, "brainium", will do better on tests. 50 students are fed 250 mg of brainium everyday for a week, and 50 students are fed 250 mg of a placebo (something that looks like brainium, but isn't) everyday for a week. After the week of treatment all students are given the same test. What is the dependent variable? Select the best answer. The students. The amount (250 mg). Time. The test scores. The type of pill (brainium or placebo) The 50 students fed the brainium. The 50 students fed the placebo.

In an experiment, I obtained 3 values which are 75, 99, 150. This shows that my values are precise. True False
A glucose monitor is an instrument that diabetics use to check their blood sugar. To use it, you insert a 'test strip' into the monitor and apply blood to it, then the blood is sucked into the instrument and the concentration of the sugars in the blood are measured. Like most instruments, it isn't 100% accurate 100% of the time. The informational pamphlet includued with the test strips say that a sample with a concentration of 7.2 mg/ml will give a reading with a standard deviation of 0.2 mg/ml. This means that when measured, a sample of blood with a 7.2 mg/ml glucose concentration will give a reading between mg/ml % of the time. mg/ml and
I was trying to set this problem where the units cancel out. You are given ampicillin, with a recommended dose of 35 mg/kg , to a child with a mass of 21 kg. If stock on hand is 250 mg/ capsule, how many capsules should be given. How should I set this conversion problem up and it's also asking to express the number of capsules as an integer
When you purchase drugs, there are many doses in the container. No one wants to drive to the store each time they have a headache! You can calculate the number of doses per container using the following formula: number of tablet per container /tablets per dose (formula) Calculate the number of doses per container for Brand X. Do not include a unit in your answer. Brand X antacid: 2 tablets / 500 mg dose 40 tablets / container Cost: $3.75 / container
A researcher is interested in developing a non-addictive sleeping pill. She has named the experimental drug Sleepatol. In designing the study to determine its’ effectiveness, the researcher chooses to use people (subjects) who have had years of trouble sleeping (chronic insomnia). The researcher divides the subjects into three groups: one group receives 25 mg. of Sleepatol, the second group receives 150 mg. of Sleepatol, while the third group receives an inert, sugar pill. Which of the following responses correctly identifies the three groups? Group of answer choices A .All three groups are experimental groups. B .The two groups that received Sleepatol are the control groups while the group receiving the inert pill is the experimental group. C .The group that receives 50 mg of Sleepatol is the experimental group and the other two are the control groups. D .The two groups that received Sleepatol are the experimental groups while the group receiving the inert pill is the…

Using your knowledge of Bayes’ Theorem, solve the following. A patient goes to see a doctor. The doctor performs a test where 95% of people who are sick test positive and 99% of the healthy people test negative. The doctor knows that only 1 percent of the people in the country are sick. (a) What is the false positive rate? (b) The false negative rate? (c) If the patient tests positive, what are the chances the patient is sick?
You have an order for 1 gram of Cefazolin in D5W 100 ml. You have added 5 ml of sterile water to the 1 gram vial to reconstitute powder. However the recommended manufacturer’s diluent amount is 10 ml of sterile water for a final concentration of 100 mg/ml. How would reconstituting the vial with 5 mls affect the concentration and the final calculated dose. Please answer with explanation ASAP. I will really upvote. Thanks
Dr. Vanier’s daughter Lexy thinks that the snacking habit alone does not cause weight loss. She believes that one needs to combine no snacking with the elimination of carbohydrates in their meals. Please explain how Dr. Vanier may test this hypothesis by describing the research design. Specify the independent variable(s), dependent variable(s), and the name of the design. Finally, describe what she needs to find (i.e., what type of effect and what it looks like) in the experiment to support her hypothesis. ( name the IV(s); 1name the DV(s); name the design; then explain the effect that will support the hypothesis)
