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 following
equation:
_________ ≤ µ ≤ __________
For this question, what is the value that is above or greater than
µ?

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 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)...

Researchers were interested in the teachers' perceptions of physical activity in children. They asked a sample of 10 elementary school grade 2 teachers to rate the physical activity level of the children in their class by filling in a questionnaire which asked about specific activities that they witness children participating in during a typical week. The questionnaire resulted in a class score out of 50 (scores could range from 0 to 50). The following is the data obtained by the...

Sleep apnea is a disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavior problems, including hyperactivity, inattention, and aggression. A common treatment for pediatric sleep apnea is the surgical removal of enlarged tonsils and adenoids that are obstructing the airways Suppose researchers at a sleep clinic are interested in the effect of surgical treatment for pediatric sleep apnea on aggressive behavior. They study 11 children without sleep apnea, 11 children with...

A psychologist was interested in the effects of different fear information on children’s beliefs about an animal. Three groups of children were shown a picture of an animal that they had never seen before (a quoll). Then one group was told a negative story (in which the quoll is described as a vicious, disease-ridden bundle of nastiness that eats children’s brains), one group a positive story (in which the quoll is described as a harmless, docile creature who likes nothing...

in comparing the engagement levels of first-year statistics students. In a previous nation-wide study, engagement levels were found to be normally distributed, with µ=60.00, σ=10.00. The lecturer collects a convenience sample of 50 first-year students and finds that her students have a mean engagement level equal to 75.54. What statistical procedure should be used, to test whether there is a significant mean difference in engagement levels between the lecturer’s first year students and the population average? a. One sample Z-test....
