Answer:
a) The dependent variable is defined as the variable that is being tested. The dependent variable here is the percentage of children who collected extra candy.
b) The data does not support the hypothesis 1 of the psychologist which states that the children would take more candy when they were alone. In the graph, percentage of children that took extra candy was higher when they were in group than when they were alone.
The data supports the hypothesis 2, which states that the children would take more candy when they were masked. From the graph, the percentage of children who took extra candy was higher when they were masked than when when they were unmasked.
c) The psychologist cannot generalize her findings to all children because she didn't use a random sampling procedure and she used children only from her neighborhood which doesn't represent the general population of children.
d) This study is not a naturalistic behaviour because the psychologist is dealing with subjects. She may also choose to manipulate the variables. Therefore we cannot call this study a naturalistic behaviour.
e) Modeling: This may play a role in the children's behaviour because the children may try to imitate what others did. The children may take extra candy because they saw others collecting extra candy.
Deindividuation: Here, the children's behaviour may be influenced by a feeling of anonymity. The children may take extra candy because they feel anonymous. Deinvuduated children feel anonymous due a feeling of loss of identity.
This explains why the percentage of chidren who took extra candy when in group was higher than that of the children who were alone.

Answer:
Technician A
Explanation:
While technician B is only partially correct, the statement of the technician A is completely true. Most shops use a spray wash cabinet, which is similar to a dishwasher that contains a strong soap and hot water solution. The solution is sprayed at parts, that are placed on a turntable, under high pressure, successfully removing oil, grease, and dirt.
As the technician B stated, some shops dip major engine parts in a hot caustic solution (but not a cold one). This method is called hot tanking, and although it cleans the engine parts well, it rarely removes all of the rust and oil paint. Due to environmental issues, this method is being used less and less.
Answer:
Explanation:
Indentured servants first arrived in America in the decade following the settlement of Jamestown by the Virginia Company in 1607.
The idea of indentured servitude was born of a need for cheap labor. The earliest settlers soon realized that they had lots of land to care for, but no one to care for it. With passage to the Colonies expensive for all but the wealthy, the Virginia Company developed the system of indentured servitude to attract workers. Indentured servants became vital to the colonial economy.
The timing of the Virginia colony was ideal. The Thirty Year's War had left Europe's economy depressed, and many skilled and unskilled laborers were without work. A new life in the New World offered a glimmer of hope; this explains how one-half to two-thirds of the immigrants who came to the American colonies arrived as indentured servants.
