We want to better understand the family dynamics of diaper changing in families with a single child. Doing "live-in" data collection, each of 40 families was observed 24 hours each day for 4 days. We collected several variables from each parent, including: 1) their age, 2) their gender, 3) the number of times they changed the child's diaper during the 4-day observation period, 4) the number of times they changed the child's diaper during the daytime of the 4-day observation period, 5) the number of times they changed the child's diaper during the evening of the 4-day observation period, 6) the number of times they changed the child's diaper during the nighttime of the 4-day observation period, 7) who they believe change diapers more often -- RH: males or females, 8) whether the diapers tended to be changed when they were dry, wet or soiled, 9) how many times they changed the child's diaper before the child began to cry and 10) how many times they changed the child's diaper after the child began to cry. For each of the following research hypotheses, tell the statistical test that would be used:--Answer part 1-7 from this information:

Researchers for the Doubleday Book Club wanted to know if reading books had an impact on how fearful people were about society. In particular, they were interested in how different genres of books affect fearfulness. To obtain this information they polled 1000 of their readers via a survey on their website. They also telephoned those who completed the web-based survey and representatives asked participants similar questions. In all, they obtained data from 325 individuals on the following variables: 1) total number of books read each month, 2) what genre of book the participant read most often, science fiction, fantasy or horror, 3) whether or not the participant felt fearful where they currently lived, and 4) whether or not they belonged to a reading group. Using 10-point scales we also asked how fearful they were about: 1) scientific topics, 2) spiritual topics and 3) supernatural topics and composed an overall fearfulness score as the average of their fearfulness about scientific, spiritual or supernatural ratings. For each of the following research hypotheses, tell the statistical test that would be used:--answer 1-7 below from this information:

1.People who belong to a reading group tend to have lower overall fearfulness scores than those to do not belong to a reading group.

a. kWG ANOVA
