Professor Thomas and his assistants should use Random assignment because the two groups result from the different amount of people to which they are exposed.
What is a Random assignment in a Psychological experiment?In psychology experiments, random assignment relates to the usage of probability processes to guarantee that each participant has the same probability of being allocated to any particular group.
The two groups result from the different amount of people in the room to which the groups are exposed, the researchers would use random assignment.
This method is used in a psychological experiment, as a chance procedure to ensure that every single participant has the same probability of getting assigned in any mentioned group.

If neon has an atomic number of 10 and an atomic mass of 20, how many neutrons does it have?.
Answer:
10
Explanation:
(20) which is the atomic mass you subtract it from the mass number to get 10
Answer:
10
Explanation
Atomic number is the amount of protons, there is an equal amount of neutrons as protons. Atomic mass is about 1 (Dalton) for both a proton and neutron. Electrons are so tiny they barely affect atomic mass at all.

How much charge is needed in the electrolysis of molten cabr2 using a current of 30. 0 a for 10. 0 hours?.
The amount of charge is needed in the electrolysis of molten cabr2 is 1.08 * 10⁶ C
Charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
Charge can either be positive or negative.
Charge (Q) is given by:
Q = It
where I is the current and t is the time.
I = 30 A, t = 10 hr = (10 * 60 * 60)s = 36000 s
Q = 30(36000) = 1.08 * 10⁶ C
The amount of charge is needed in the electrolysis of molten cabr2 is 1.08 * 10⁶ C

Select the statements that would allow you to conclude that the relationship between a response variable y and an explanatory variable x is linear.
Here are the statements that would allow you to conclude that the relationship between a response variable y and an explanatory variable x is linear:
- The graph of y versus x shows the points lying approximately along a straight line.
- The correlation coefficient r between x and y is close to +1 or -1.
- The regression equation relating y to x is of the form y = bx + a, where b and a are constants.
- The residuals (differences between observed and predicted values of y) show no systematic pattern when plotted against x.
- An F-test or t-test on the regression model gives a statistically significant result for the coefficient of x.
- Adding higher order terms of x (like x^2, x^3 etc) to the regression equation does not significantly improve the model fit.
- There are no statistical interactions detected between x and other explanatory variables when modeling y.
In summary, signs of a linear relationship include a straight line pattern in the data plot, a high correlation coefficient, a significant linear regression model, random residuals, and lack of improvement by adding nonlinear terms or interactions. These indicators would allow you to conclude that the relationship between y and x is best described by a linear model.
Referring to figure 1, explain the process illustrated between step 1 and step 2.
The process illustrated is the elongation of an amino acid chain.
What does the figure illustrate?Step 1. This figure shows the process of synthesis of an amino acid change, which occurs in the ribosome. In this, you can observe two transfer RNA attached to one aminoacid chain represented by the letters.Step 2. This figure shows the two aminoacid chains that have joined to create one unique amino acid chain, due to this, one of the transfer RNA is now free.How does this occur?This is possible due to translation elongation. In this process, amino acids are bound together by pairing up two transfer RNA. Moreover, this requires an elongation factor that makes it possible to add aminoacids to a chain and therefore make the chain longer.
Note: This question is incomplete because the figure is not provided. Below, I attached the figure.

Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. A. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9? b. How long will it take to transfer all the sectors of track 8 to the corresponding sectors of track 9?.
Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
A factory manager selected a random sample of parts produced on an old assembly line and a random sample of parts produced on a new assembly line. The difference between the sample proportion of defective parts made on the old assembly line and the sample proportion of defective parts made on the new assembly line (old minus new) was 0. 6. Under the assumption that all conditions for inference were met, a hypothesis test was conducted with the alternative hypothesis being the proportion of defective parts made on the old assembly line is greater than that of the new assembly line. The p-value of the test was 0. 18.
Considering the p-value of the test, it is found that there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.
What are the hypothesis tested?At the null hypothesis, it is tested that the proportion of defective parts made on the old assembly line is not greater than that of the new assembly line, that is:
[tex]H_0: p_O = p_N[/tex]
At the alternative hypothesis, it is tested if the proportion is greater, that is:
[tex]H_1: p_O > p_N[/tex]
What is the decision?The p-value is greater than the standard significance level of 0.05, hence we do not reject the null hypothesis, that is, there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.

The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹
The chemical reaction :
C₂H₅Cl ------> C₂H₄(g) + HCl(g)
Determine the value and unit of the rate constant ( K )let the rate of reaction be expressed as
R = k [ C₂H₅Cl ]ⁿ ---- ( 1 )
where : n = order
k = rate constant
From the table
2 = 2ⁿ
therefore n = 1
Hence we can rewrite equation ( 1 ) as
R = k [ C₂H₅Cl ] ¹ ( first order reaction ) ---- ( 2 )
Next step : substitute the value of C₂H₅Cl and initial rate into equation 2
0.630 * 10⁻³⁰ = k ( 0.1 ) ¹ M
Therefore : K = 0.630 * 10⁻²⁹ s⁻¹
