define U=x+y, V=x-y.

find the joint and marginal pdf of U and V

Place the following activities in their correct order:

1.) Designing an experiment that yields data

2.) Deciding how much data to collect

3.) Running the experiment that generates the data

4.) Collecting the data

5.) Interpreting the data to validate or discredit a model

5. Why do different atoms/ions emit different colors of light?

2. An unknown solution tested in this experiment gave a yellow green flame test. Do you expect to observe a precipitate with the reagents used in Part C of this experiment?

A famous scientist, Mendel, conducted a genetic experiment with peas. One sample

from this experiment consisted of 152 yellow peas out of 580 peas. Calculate a 95%

confidence interval for the percentage of yellow peas. Also, find the estimation and

the margin of error.

1. Suppose that the probability that a certain experiment will be successful is 0.4, and let X denote the denote the number of successes that are obtained in 15 independent performances of the experiment. What is the probability of getting at least 12 successes experiments? What is the expected value and variance for the described distribution?

Before going in the cells, a coronavirus must first find a receptor protein on the cell’s carbohydrate layer. Design/Propose a simple experiment that prevents the virus entering into a cell. If coronavirus is already inside the cell, design an experiment to block it from forming varions.

3. a) What is the significance that some of the alpha particles were strongly back-scattered in the Rutherford scattering experiment? b) Describe the model of the atom Rutherford deduced from his experiment. c) What problem did a classical interpretation of this model present?

1. Describe the mouse “survival” experiment conducted by Hoesktra and colleagues: what was it testing, how was it performed, what were the results, and what were the limitations to this experiment (i.e. what could the researchers not do and/or what research questions remained to be explored with further experiments)?
