(a) TV stations use ratings to decide which shows to keep or cancel. Therefore, the A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ: 1. Identify the variable. 2. Identify the two populations. 3. Identify the pairs. 4. Identify the paired-difference variable.
A recent study on driving behavior examined whether the combination of high driving skills and low safety skills is dangerous. Participants were classified as high or low in driving skill based on responses to a driver-skill inventory, then classified as high or low in safety skill based on responses to a driver-aggression scale. An overall measure of driving risk was obtained by combining several variables such as number of accidents, tickets, tendency to speed, etc. The following data were obtained. Use a 2 x 2 ANOVA with the .05 significance level to evaluate the results. What cutoff score(s) should be used? Driving Skill Low High Safety Skill Low M1=5 M2=4.5 S1=2.7 S2=3.8 N1=6 N2=6 HIgh M3=3 M4=3.5 S3=2.9 S4=2.5 N3=6 N4=6 Group of answer choices +4.35 +3.40 +3.49 +4.26
A County Board of Supervisors has appointed an urban planning committee to evaluate proposed community development projects. The committee is analyzing, among other things, data on household incomes in two cities within the county. They have collected data on the income of 77 households in each of the two cities. The histograms below show the distributions of the two sets of incomes (in thousands of dollars). Each histogram shows household income on the horizontal axis and number of households on the vertical axis. The means and standard deviations for the data sets are also given.

Verbal intelligence was a topic that Jamie was very interested in. She conducted a study to see whether children with ADHD had lower scores on measures of verbal intelligence than those without ADHD. She divided children in her study into 4 groups- those clearly diagnosed with ADHD- combined type, those clearly diagnosed with ADHD- inattentive type, those with ADHD symptoms but not clearly diagnosed, and those without ADHD. Then she measured their scores on the Reading Comprehension task, Vocabulary task and Writing Task. What type of statistic did she run? A 4 way MANOVA A 4 way MANCOVA A one way MANOVA A Factorial MANOVA
Considering how the data is skewed, which value best represents the center of {12.8, 5.7, 7.9, 1.3, 3.2, 2.8}? 5.62 O 4.45 4.22 O 11.55
