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)?

Thermodynamics of potassium nitrate dissolving in water experiment post-lab questions: What does the sign of the delta G tell you about the dissolution process for this experiment? Is the dissolution process spontaneous at all temperature? If not at what temperature does this spontaneity change?

Marie earned her bachelor’s degree in HIM. After working intraditional HIM roles for a few years, she decided that she wanted tobe involved in the selection and implementation of the EHR andother healthcare information systems. Marie went back to school andearned her master’s degree in health informatics. After graduation,Marie worked for an information system vendor for several years.She decided to take another turn in her career path and become aprofessor in an accredited HIM program. She took a position as afaculty member in a bachelor’s-level HIM program. Marie nowteaches the information system courses for the HIM program and isable to give the students real world examples from her experience inthe traditional HIM departments and the information system vendor.Marie enjoyed her position so much that after teaching for a while,Marie went back to school again to earn her doctorate degree inadult education.

1. Identify how this Real-World Case ties to this chapter.

2. In the Real-World Case, Marie earned a bachelor’s degree, a master’s degree, and a doctoral degree. Do you think that some or all of the new roles discussed in this chapter will require graduate education? Why or why not? How do these roles tie into HIM Reimagined?

Three fair dice (black, white and red) are tossed simultaneously and the value recorded as an ordered triple y = (yb, yw, yr), which is a point in S.

Let A1, A2, A3 be the events A1 = {(yb, yw, yr) : yb = yw} A2 = {(yb, yw, yr) : yb = yr} A3 = {(yb, yw, yr) : yw = yr}

(i) What is the sample space S for this experiment? How many points or elementary events does it contain?

(ii) How many points are contained in the event A1?

(iii) How many points are contained in the event A1 ∪ A2?

(iv) How many points are contained in the event A1 ∪ A2 ∪ A3?

(v) How many points are contained in the event A1 ∩ A2?

(vi) How many points are contained in the event A1 ∩ A2 ∩ A3?

(vii) The events A1 and A2 ∩ A3 are disjoint. (True or False?)

(viii) The events A1 and A2 are independent. (True or False?)

(viii) The events A1 and A3 are independent. (True or False?)

(ix) The events A2 and A3 are independent. (True or False?)

(x) The events A1, A2 and A3 are independent. (True or False?)

Lab: Exploration of Avogadro's Law-Determination of Percentage of Sodium Bicarbonate in an Alka-Seltzer Tablet

1) One concern with setting up a closed system experiment where gas is evolved during a reaction is the presence of leaks (another concern is that the system will explode if too much gas evolves!). We know that some leaking of pressure occurs because after a maximum pressure is achieved it slowly starts to decrease with time. Will a leak during gas evolution overstate or understate the amount of sodium bicarbonate in an Alka-Seltzer tablet and why?

2)In our rearranged Ideal Gas Law Δn=(ΔPV)/(RT) we considered V and T to remain constant. Is this a reasonable assumption and why? Assuming that T increased as a function of the reaction, would this cause an overestimation or underestimation of the amount of sodium bicarbonate?

3) To calculate the amount of sodium bicarbonate, we assume that there was enough citric acid to react completely with the sodium bicarbonate. However, if the citric acid is the limiting reagent, then the calculated amount for sodium bicarbonate would be incorrect. How could we experimentally test this possibility? Describe in two sentences how you would change the reaction conditions to account for this.
