1.Most supermarkets across the United States have invested heavily in opticalscanner systems to expedite customer checkout, increase checkout productivity, and improveproduct accountability. These systems are not 100% effective, items often have to scan severaltimes. Sometimes items are entered into the manual cash register because the scanner cannotread the item number. The following data are from an experiment in which a supermarketselected 20 of the best checkers and measured their productivity both when using a scannerand when working manually. In general, do optical scanners register significantly more itemsthan manual entry systems do?

Suppose you are conducting a study about how the average US worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, emails, and social networking websites, as well as how much time they spend socializing with coworkers versus actually working. The most recent census provides data for the entire population of US workers on variables such as travel time to work, time spent at work, and break time at work. The census, however, does not include data on the variables you are interested in, so you obtain a random sample of 102 full-time workers in the United States and ask about personal calls, emails, and so forth. You are curious about how your sample compares with the census, so you also ask the workers the same questions about work that are asked in the census. Suppose the mean travel time to work from the most recent census is 24.1 minutes, with a standard deviation of 4.5 minutes. Your sample of 102 US workers…

It has often been suggested that students study 2 hours per week outside of class for every credit hour a class is worth. For example, students taking a 3 hour class are expected to study 6 hours for that class per week outside of class. A student wondered if her fellow classmates followed that guideline. She randomly sampled 100 students from her university and asked each to estimate the number of hours they studied outside of class each week (on average) that term and the number of credit hours they were taking that term. A 95% confidence interval for the average number of hours studied outside of class per week per credit hour taken for students at this university is (1.3,1.9). Based on this confidence interval, which of the following is true? Choose the correct answer below. O A. Because the difference in the bounds of the confidence interval is 0.6, it does not appear that students at this university are studying the recommended 2 hours per week per credit hour, on average.

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).

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
