what was the purpose/hypotheses, basic method, findings, limitations/criticisms, issues, and how can we use the information today from the Bobo Doll experiment? What topic in social psychology did it help define?

Albert Bandura's Bobo Doll experiment changed the way we think about modeling and social learning. In your opinion, do you think that children learn violent behavior from playing video games?

Define the term “Historical Control” and explain its relevance to issues surrounding the differences between a “Randomized Controlled Experiment” and an “Observational Study”.

Explain the difference between a “quantitative variable” and a “qualitative variable” and give an example of each.

Experiment 1: Measure the pH of Acids

Lab Results

Record your observations in the table below.

Data Analysis

For each test tube, calculate the concentration of H₃O and pH. You can use the following formula to determine the concentration of HCl.
M₁ x V₁ = M₂ x V₂
where M₁ and V₁ are the molarity and volume of the first solution and M₂ and V₂ are the molarity and volume of the second solution.
Given that HCl is a strong acid, the H₃O concentration is equal to the HCl concentration except at very low concentrations (test tube 6 and 7) where the H₃O from the dissociation of water (1.00*10^-7) becomes significant.

Experiment 2: Measure the pH of Bases

Lab Results

Record your observations in the table below.

Data Analysis

For each test tube, calculate the concentration of NaOH, OH^–, H₃O, and pH. You can use the following formula to determine the concentration of NaOH.
where M₁ and V₁ are the molarity and volume of the first solution and M₂ and V₂ are the molarity and volume of the second solution.
M₁ x V₁ = M₂ x V₂
Given that NaOH is a strong base, the HO^– concentration is equal to the NaOH concentration except at very low concentrations (test tube 6 and 7) where the HO^– from the dissociation of water (1.00*10^-7) becomes significant.

Conclusion

1- Why do you think some of the indicators used in experiment 2 were different than the ones used in experiment 1?

2- Suppose a student mixed his HCl and NaOH solution and decided to use bromothymol blue to figure out which is which. Which test tube in the figure below contains NaOH?

A: Yellow Test Tube

B: Blue Test Tube

A double-slit experiment yields an interference pattern due to the path length difference from light traveling through one slit versus the other. Why does a single slit show a diffraction pattern?

The experiment of rolling a fair six-sided die twice and looking at the values of the faces that are facing up, has the following sample space.

For example, the result (1,2) implies that the face that is up from the first die shows the value 1 and the value of the face that is up from the second die is 2.

sample space of tossing 2 die

A pair of dice is thrown.

Let X = the number of multiples of 2.

Complete the table to construct a probability distribution for X using the sample space from the experiment of rolling two fair six-sided dice.

Note: Your answers should be approximate decimals to 4 places.

Probability distribution for X = num. of multiples of 2

Question: Write the reaction(s), with the reactant and products' structures to describe the following experiment.

In this experiment you will steam distill clove oil from freshly ground cloves. Following the distillation, clove oil and water will be present in the receiving flask. Because clove oil will be a minor fraction of the distillate, the clove oil must be extracted from the water into an organic solvent such as dichloromethane. Removing the dicholormethane layer leaves clove oil as the product.

The steps to be taken are:

1. Place ground cloves of garlic and water in a distilling flask

2. Distill the mixture (steam distillation)

3. Extract the clove oil into the dicholormethane and dry this with anhydrous NA_​2SO₄

_​​4. Remove the dichloromethane from the clove oil by distillation and finally weight the clove oil

[12] In an experiment on human behavior, a psychologist asks four men and four women to enter a room and sit at a rectangular table. This table has three seats on each of the longer sides of the table, and one seat at each end of the table. The seats at the end of the table are considered to be the dominant seats. (A diagram may help you to visualize this).

a. If the people choose their seats randomly, determine the probability distribution for the random variable X, where X represents the number of women occupying the end seats. [4]

b. Determine E(X) and Var(X). [5]

c. In 15 independent repetitions of the experiment involving different people each time, calculate the probability that women occupy both end seats 2 or more times. [3]
