2. Abоut 13% оf the United Stаtes pоpulаtion is left-hаnded. Suppose that a researcher speculates that individuals with schizophrenia are more likely to be left-handed than the US population. The researcher surveys 104 individuals with schizophrenia and finds that 22 of them are left-handed. Based on this sample, is there enough evidence that the population proportion of individuals with schizophrenia who are left-handed is more than the 13% (or 0.13). (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (b) What type of statistical test should be used for this situation?

Although only 7 to 10 years old, they are forced to work 12 to 14 hours a day. Most important, child labor is quite cheap; children are generally paid less than one-third of the adult wage. Not surprisingly, when children are given jobs, their parents may lose theirs.
