Temperament is not usually considered to change throughout life as it is biologically based and remains fairly stable. It underlies much of our personality.
The statement that 'Temperament is an aspect of personality that often changes throughout someone’s life' is false. Temperament is generally considered to be biologically based and remains fairly stable throughout life. It refers to individual differences in behavior which are apparent in early childhood and are comparatively stable across different situations and over time. It can be seen as the foundation upon which the personality is built. Examples of temperament traits include sensory sensitivity, activity level, emotional reactivity, and sociability.

Explanation:
True statements about hypothesis testing include:
1. **Hypothesis Testing is a Statistical Method:** Hypothesis testing is a statistical method used to make inferences about populations based on sample data. It involves making educated guesses (hypotheses) about population parameters and using sample data to test these hypotheses.
2. **Two Hypotheses:** In hypothesis testing, there are typically two hypotheses involved:
- **Null Hypothesis (H0):** This is the default or initial hypothesis. It often represents a statement of no effect, no difference, or no change.
- **Alternative Hypothesis (Ha or H1):** This is the hypothesis that researchers aim to support. It represents the opposite of the null hypothesis and often indicates an effect, difference, or change.
3. **Significance Level:** Researchers set a significance level (alpha, often denoted as α) before conducting hypothesis testing. This significance level represents the probability of making a Type I error (rejecting a true null hypothesis). Common significance levels are 0.05 (5%) or 0.01 (1%).
4. **Test Statistic:** In hypothesis testing, a test statistic is calculated from the sample data. The choice of test statistic depends on the type of data and the hypothesis being tested.
5. **P-Value:** The p-value is a key result of hypothesis testing. It represents the probability of obtaining the observed results (or more extreme results) under the assumption that the null hypothesis is true. A smaller p-value indicates stronger evidence against the null hypothesis.
6. **Comparison with Significance Level:** Researchers compare the calculated p-value with the significance level (α). If the p-value is less than or equal to α, the null hypothesis is rejected in favor of the alternative hypothesis. If the p-value is greater than α, there is insufficient evidence to reject the null hypothesis.
7. **Conclusion:** Based on the comparison of the p-value and the significance level, a conclusion is drawn. If the null hypothesis is rejected, it suggests that the alternative hypothesis is supported. If the null hypothesis is not rejected, there is insufficient evidence to support the alternative hypothesis.
8. **Errors:** Hypothesis testing involves the possibility of two types of errors:
- **Type I Error:** This occurs when the null hypothesis is rejected when it is actually true (false positive).
- **Type II Error:** This occurs when the null hypothesis is not rejected when it is actually false (false negative).
9. **Sample Size:** The power of hypothesis testing depends on the sample size. Larger sample sizes are more likely to detect smaller effects or differences if they exist.
10. **Statistical Tests:** There are various statistical tests and methods for hypothesis testing, including t-tests, chi-squared tests, ANOVA, regression analysis, and more. The choice of test depends on the research question and the type of data being analyzed.
11. **Replicability:** Hypothesis testing is an essential part of the scientific method, and research findings
Answer and Explanation:
Risperidone is a potent atypical antipsychotic drug. It is a selective monoaminergic antagonist with unique properties. It has high affinity for 5-HT2 serotoninergic and D2 dopaminergic receptors. Risperidone also binds to alpha-1 receptors adrenergic and, with lower affinity, histamine H1 and alpha2 adrenergic receptors. Risperidone does not have affinity for cholinergic receptors. Although risperidone is a potent D2 antagonist, this is considered responsible for improving the positive symptoms of schizophrenia, its depressant effect on motor and catalepsy inducer is less potent than classical neuroleptics.
It is most often used in the treatment of delusional psychoses, including schizophrenia. However, risperidone, like other atypical antipsychotics, is also used to treat some forms of bipolar disorder, depressive psychosis, obsessive compulsive disorder, and Tourette's syndrome. In the United States, it has also been approved for the treatment of irritability in children and adolescents (although is not recommended for the treatment of autism spectrum disorders and milder forms of autism due to its effects).

b. Immunotherapy
c. Surgery
d. Hormones
Surgery is the treatment method that directly removes cancer. Other treatments like chemotherapy and immunotherapy treat cancer but in different ways. Hormones, though sometimes used in treatment, aim to slow or stop cancer growth.
In the context of cancer treatment, we can say that surgery is the method that directly removes cancer. It is a common form of treatment usually aimed at removing the entire tumor. However, the effectiveness of surgery often depends on the type and stage of cancer. While options like chemotherapy and immunotherapy treat cancer as well, they do so in different ways. Chemotherapy uses drugs to kill cancer cells, whereas immunotherapy helps the immune system fight cancer. Lastly, hormones can sometimes be used in cancer treatment, but they do not remove cancer; they aim to stop or slow the growth of cancer cells.
