Reading From Eliot Aronson The Social Animal Aronson Defines

Reading from Eliot Aronson The Social Animal, Aronson defines prejudice as a hostile or negative attitude toward a distinguishable group based on generalizations derived from faulty or incomplete information. This text explores four basic causes of prejudice: (1) economic and political competition or conflict, (2) displaced aggression, (3) personality needs, and (4) conformity to existing social norms. These causes may not be mutually exclusive; they can operate simultaneously. Understanding their importance is essential since any action recommended to reduce prejudice relies on identifying its major causes.

If one believes that bigotry is deeply ingrained in human personality, they might conclude that, unless significant psychotherapy occurs, most prejudiced individuals will remain so. This perspective could lead to skepticism regarding efforts to reduce prejudice through mechanisms like decreasing competitiveness or resisting conformity pressures. While prejudice can disadvantage minorities, it can also benefit them in certain contexts. Stereotyping, a common cognitive process, is not inherently negative and sometimes serves as a mental shortcut for processing complex information. However, individuals learn specific prejudices through social and cultural contexts.

Introduction

This paper aims to address the hypothesis tests for two populations based on the provided scenarios. The primary focus is on independent and dependent samples regarding two different situations: effects of lead levels on IQ scores and box office earnings of two Harry Potter movies. Utilizing statistical analysis, this paper will evaluate hypotheses, critical values, test statistics, and p-values while making the findings accessible to general audiences.

Independent Samples: Effects of Lead Levels on IQ Scores

In testing the effect of lead levels on intelligence, the first step is to formulate the hypotheses:

  • Null Hypothesis (H0): μ1 ≤ μ2 (The mean IQ score of individuals with low lead levels is not greater than that of individuals with high lead levels)
  • Alternative Hypothesis (H1): μ1 > μ2 (The mean IQ score of individuals with low lead levels is greater than that of individuals with high lead levels)

This test is right-tailed as we are checking if the mean IQ is greater, implying a one-sided test.

Given:

  • Sample size (n1): 78
  • Sample standard deviations (s1): 15.34, s2: 8.99

Assuming normal distribution, we can calculate the test statistic using a t-test formula for unequal variances:

Test Statistic (t) = (X̄1 - X̄2) / √((s1²/n1) + (s2²/n2)).

Next, we recognize the significance level (α) is 0.05. Thus, we will find the critical value and p-value using a t-distribution table. Calculating based on the given data leads to:

  • Critical Value: ...
  • Test Statistic: ...
  • p-value: ...

Based on the test statistic and p-value, one would make a decision regarding the null hypothesis. If the p-value is less than alpha (0.05), we reject the null hypothesis. In conclusion, if we reject the null hypothesis, we can state that there is statistical evidence supporting that individuals with low lead levels have higher IQ scores than those with high lead levels.

Dependent Samples: Box Office Earnings of Harry Potter Movies

For the dependent samples test, we evaluate the first few days' earnings of two movies: Harry Potter and the Half-Blood Prince, and Harry Potter and the Order of the Phoenix. Here we formulate the hypotheses as follows:

  • Null Hypothesis (H0): μD ≤ 0 (The mean difference in earnings is not greater than zero)
  • Alternative Hypothesis (H1): μD > 0 (The mean difference in earnings is greater than zero)

This also is a right-tailed test. The days of release earnings are as follows:

  • Half-Blood Prince: 44.2, 22.8, 29.0, ...
  • Order of the Phoenix: 58.4, 26.3, 21.4, ...

Calculating the mean difference of the paired samples gives us the required information. The test statistic can also be calculated using paired t-tests. The calculations yield:

  • Critical Value: ...
  • Test Statistic: ...
  • p-value: ...

Using the p-value method, we make the decision concerning the null hypothesis. If the p-value is less than 0.05, we would reject it, concluding that Harry Potter and the Half-Blood Prince garnered more box office earnings than the Order of the Phoenix in its initial release days.

Conclusion

In summary, both independent and dependent samples provide significant insights into the respective hypotheses regarding lead levels and film earnings. In interpreting these results, it is crucial to connect statistical significance back to practical impacts on intelligence and consumer behavior.
