Homework Answers
3. IV is the categorical variable , instrument playing status of the child (i.e. whether the children plays the instrument or not)
4. DV is the IQ
5. μ1 is the true mean IQ of children who plays instrument

9. A researcher is interested in whether child aggressive behavior changes after they see another child who has something that they want (but do not have). She devises an experiment where children come into her lab and are given worn and broken toys to play with. After a short time, another child is brought in the room and is given new, shiny toys to play with. The researcher wants to know whether there are changes in aggressive behavior among the...

A psychologist is interested in knowing whether adults who were bullied as children differ from the general population in terms of their empathy for others. On a questionnaire designed to measure empathy, the mean score for the general population is 30.6. Random sampling of 25 scores obtained from individuals who were bullied yielded a sample mean of 39.5 and a sample standard deviation of 6.6. Test at the .05 level of significance. Suppose that the value of your calculated (obtained)...

A psychologist is interested in knowing whether adults who were bullied as children differ from the general population in terms of their empathy for others. On a questionnaire designed to measure empathy, the mean score for the general population is 53.48. Random sampling of 25 scores obtained from individuals who were bullied yielded a mean of 97.86 and a standard deviation of 5.44. Calculate the 99% confidence interval. Steps: As you know, two values will be required to complete the...

A psychologist is interested in knowing whether adults who were bullied as children differ from the general population in terms of their empathy for others. On a questionnaire designed to measure empathy, the mean score for the general population is 95.71. Random sampling of 76 scores obtained from individuals who were bullied yielded a mean of 75.37 and a standard deviation of 22.87. (Use these numbers only for this question!) Suppose you want to calculate the 99% confidence interval. The...

A researcher is interested in whether students who are musicians have higher intelligence scores than those in the general population. The researcher predicts that playing a musical instrument is associated with higher intelligence test scores. The researcher selects a sample of 75 musicians from local high schools and gives them an intelligence test. She compares their average intelligence to that of students in the general population and finds that zobt = +1.92. This is a _____ test and the researcher...

A researcher is interested in whether students who are musicians have higher intelligence test scores than students in the general population. The researcher predicts that playing a musical instrument is associated with higher intelligence scores. The researcher selects a sample of 75 musicians from local high schools and gives them an intelligence test. The mean for the sample is 105. The mean for the general population (μ) is 100 with a standard deviation (σ) of 15. What is zobtfor this...

Question 7 2 pts A researcher is interested in whether there are significant differences between 5-year olds, 10-year olds, and 15-year olds in working memory scores. In planning his hypothesis tests, the researcher identified age as the independent variable and working memory as his dependent variable. Can the researcher use an independent-samples t test to test his hypothesis? Why or why not? Yes, because there is one nominal independent variable and one scale dependent variable No, because the independent variable...
