Answer:
trade agreements with other countries
Explanation:
The invention of the automobile was in the EARLY 1900s, not the late. The development of the computer did not really effect / impact lives until 1990s and so does not really fit the question. The shopping malls could be an answer, but I think trade agreements is the best answer.
if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

Answer:
Anchoring bias
Explanation:
Selective perception is the tendency not to notice and more quickly forget stimuli that cause emotional discomfort and contradict our prior beliefs. For example, a teacher may have a favorite student because they are biased by in-group favoritism. The teacher ignores the student's poor attainment.
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or strengthens one's prior personal beliefs or hypotheses. It is a type of cognitive bias.
Framing bias refers to the observation that the manner in which data is presented can affect decision making. The most famous example of framing bias is Mark Twain's story of Tom Sawyer whitewashing the fence. By framing the chore in positive terms, he got his friends to pay him for the “privilege” of doing his work.
The anchoring effect is a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information offered (the “anchor”) when making decisions. During decision making, anchoring occurs when individuals use an initial piece of information to make subsequent judgments.
