For 6 months we worked with a group of 15 severely mentally handicapped individuals in an attempt to teach them self-care through imitation. For a second 6-month period, we used physically guided practice with the same individuals. For each 6-month session, we collected ratings on the level of required assistance (high = bad) for each person. The data for each individual follows (on the next page). Was the assistance significantly reduced in the second 6-month period? (use alpha=0.05) %3D Subject # Imitation 1 3 4. 6. 7. 8. 9. 10 11 12 13 14 15 14 11 19 8. 4 6. 12 14 17 18 0. 8. 6.

A researcher is interested in whether an alternative treatment, "Attention Focus Formula", effectively reduces Attention Deficit Disorder (ADD). The researcher has access to 10 children who have all been diagnosed with ADD. He places them on a regimen of"Attention Focus Formula" for a period of six weeks. Afterwards, he gives the children the "Attention Deficit Disorders Evaluation Scale" (ADDES), which is a 43- item test. Population scores on the ADDES are known to have a standard deviation of 12 and a score of 30 is average for children who have a clinical level of ADD. The following ADDES scores were obtained from the 10 children after being given Attention Focus for six weeks. child # 4. 7. 8. 6. 10 score on 24 21 25 28 30 29 25 31 22 28 ADDES Can the researcher conclude that Attention focus Formula was effective in reducing ADD?

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat.   Before opening the data, what would you hypothesize about this research question?   Open the data set.

both questions (a) and (b) pleasee Twelve inmates in a particular prison took part in an anger management class. Before it began, the median score on an anger control assessment of the group was 42 (out of a maximum of 60). After the six month class, the participants scores on the same assessment were 35, 41, 40, 44, 57, 36, 39, 47, 58, 39, 42, 39. (a) - the course was designed to lower anger control scores. Perform a sign test on whether the course was successful using a = 0.05 (b) Construct a boxplot of the data and explain briefly why a sign test is appropriate to use in this case
