Design an experiment to determine the strength of the magnetic field of Earth using the available equipment.

Available equipment: A large coil of wire (with stand in the center), compass, ammeter, 10Ω and 50Ω resistors, power supply, ruler.

A) Perform the experiment and record your measurement and calculations in an appropriate format. Be explicit about what model you're using to calculate the magnetic field. Vector diagrams may assists you. Include important measurements. Determine the magnitude of the Earth's magnetic field.

B) Identify at least 3 sources of error in your experiment and evaluate how they affect your data. Identify at least 1 shortcoming in your experimental design and what you would do to fit it, Summarize these. Hints: Just saying human error is not acceptable.

In the Dumas Method for determining the molar mass of an unknown liquid with a boiling point less than water, the liquid is vaporized in a bulb (whose volume is precisely known) that is immerse in a water bath. The bulb is sealed after all the liquid has been evaporated. The bulb is cooled and the gas that has filled the container condenses. The bulb is weighed and the weight of the liquid in the bulb is determined by weighing the bulb before the experiment and after the experiment. The following data for an unknown liquid is obtained using the Dumas Method:

The gas in the Dumas bulb must be

Does reaction time (measured in seconds) depend on how much coffee is consumed? Researchers design an experiment in which subjects are instructed to look at a computer screen and respond as quickly as possible—by pressing a button—as soon as a particular stimulus appears on the computer screen. Prior to responding to the computer stimulus, subjects are either randomly assigned to drink no coffee, to drink one cup of coffee, or to drink two cups of coffee. It is observed that those subjects who drink the most coffee have the shortest reaction times (or react faster), on average, than those who drink no coffee at all. In this experiment, the response variable

A. is the variable being manipulated by the experimenter.

B. is a categorical variable.

C. is a quantitative variable.

D. is the number of subjects who took part in the experiment. E. is the stimulus that appeared on the computer screen

hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following:

1. A detailed discussion of your experimental design.
2. How is randomization used in your sampling or assignment strategy?
3. The type of inferential test utilized in your experiment.
4. A formal statement of the null and alternative hypothesis for your test.
5. A confidence interval for estimating the parameter in your test.
6. An interpretation of your p-value and confidence interval, including what they mean in context of your experimental design

Can you do bullets for each answer, because I get confused as to which is the answer for which portion.

A standard 52 card deck is being used in an exciting experiment! A card is drawn randomly from the deck, its

information is recorded, then the card is returned to the deck and it is thoroughly shuffled.

(a) Determine the probability that if we perform this process 6 times, we get exactly 3 diamonds, and exactly 1 spade.

(b) If we repeat this experiment 11 times, what is the probability that we get three times as many clubs as hearts. (c) Determine the probability that if this process is repeated 5 times, there will be exactly 2 diamonds drawn,

and at most 1 jack.
(d) Suppose we repeat this experiment 7 times. Determine the probability that we draw exactly 3 clubs and

exactly 1 heart, if we know that we drew exactly 2 red cards.

1. Suzie was curious about how productive college sophomores attending Penn State Main campus are in working on a math worksheet when listening to music. She decided to conduct an experiment. She picked five of her closest sophomore friends to participate. She had each of them bring a phone and headphones to listen to music. She gave them all a copy of the same calculus worksheet to work on and timed how long it took them to finish it correctly.

a. List three things wrong with Suzie’s experiment.

2. Explain the difference between a independent variable and a dependent variable. a. Provide an example of each in contexts of an experiment.

3. Give two reasons why ratio measurement is the best measurement system.

4. Define a random sample and convenience sample.

1a) Let an experiment consist of rolling three standard 6-sided dice.

i) Compute the expected value of the sum of the rolls.
ii) Compute the variance of the sum of the rolls.
iii) If X represents the maximum value that appears in the two rolls, what is the expected value of X?

1b) Consider an experiment where a fair die is rolled repeatedly until the first time a 3 is observed.
  
i) What is the sample space for this experiment? What is the probability that the die turns up a 3 after i rolls?
ii) What is the expected number of times we roll the die?
iii) Let E be the event that the first time a 3 turns up is after an even number of rolls. What set of outcomes belong to this event? What is the probability that Eoccurs?

Q1. Cell survival curves

Suppose you did an experiment to generate a cell survival curve.

a) Describe what steps you would take to do the experiment.

b) What is meant by plating efficiency?

c) In your experiment you irradiate cells using 6 MV photons on a linear accelerator. You collect the data shown in the table below. Plot cell survival as a function of dose and use the linear-quadratic model to fit the data.

d) Determine the alpha/beta ratio from the curve fit. Is this an early responding or late responding cell line?
