- Temperature has a direct correlation with aggression. Knowing this, a researcher predicts that participants completing a frustrating task will express more aggression when they are in a 90-degree room than a 70-degree room. The researcher finds t(20) = 2.33, p < .05. Knowing this, what should his research conclusion be? A. That people were equally aggressive in the 70-degree room and 90-degree room. B. That people were more aggressive in the 90-degree room than the 70-degree room. C. Unfortunately, there is not enough information to make a full conclusion. D. That people were more aggressive in the 70-degree room than the 90-degree room.22. The Muller-Lyer illusion is shown in the figure. Although the two horizontal lines are the same length, the line on the left appears to be much longer. To examine the strength of this illusion, Gillam and Chambers (1985) recruited 10 participants who repro- duced the length of the horizontal line in the left panel of the figure. The strength of the illusion was mea- sured by how much longer the reproduced line was than the actual length of the line in the figure. Below are data like those observed by the researchers. Each value represents how much longer (in millimeters) the reproduced line was than the line in the figure. 2.08 2.7 3.42 1.59 2.04 2.87 3.36 0.49 3.82 3.91 a. Use a one-tailed hypothesis test with a 5 .01 to demonstrate that the individuals in the sample sig- nificantly overestimate the true length of the line. (Note: Accurate estimation would produce a mean of m 5 0 millimeters.) b.

- Two students have started a business to seal driveways during the summer months. They rent a pickup truck and a power sprayer. With this they will use a tar-based spray to seal asphalt driveways. Past experience has shown that the best time to sign up customers is to ring their doorbells between 5:00 and 8:00 p.m. on any weekday evening. Any jobs that they obtain will be completed the next day. In the months of June, July and August they find that they get an average of 2 customers per hour ringing doorbells. a) What is the probability that they will get from 5 to 9 jobs in an evening of soliciting? The probability that they will get from 5 to 9 jobs in an evening of soliciting is? b) They charge $25 per driveway. If the truck costs $50 per day, and the spraying equipment costs $20 per day and the material to seal one driveway costs $5, what is the probability that they will make a profit on any given day?
