You recently received a job with a company that manufactures an automobile antitheft device. To conduct an advertising campaign for the product, you need to make a claim about the number of automobile thefts per year. Since the population of various cities in the United States varies, you decide to use rates per 10,000 people. (The rates are based on the number of people living in the cities.) Your boss said that last year the theft rate per 10,000 people was 44 vehicles. You want to see if it has changed. The following are rates per 10,000 people for 36 randomly selected locations in the United States.

The bad news, says CDC is that average BMI (body mass index, a weight-for-height formula used to measure obesity) has increased among adults...” Boston is considered one of America’s healthiest cities – is the weight gain since 1960 similar in Boston? A sample of n=28 adults suggested a mean increase of 19.5 pounds over the mean recorded in 1960 with a standard deviation of 8.6 pounds. Is Boston statistically significantly different in terms of weight gain from the national mean since 1960? Run the appropriate test at a 5% level of significance.

- The human nervous system is extremely sensitive to changes in the environment. Stimuli that remain the same do not demand the same amount of attention as those that are new. You are a human factors psychologist working for a large automobile manufacturer. You have been assigned the task of determining what type of hot-engine warning system will be used on the next generation of small pickup trucks. The designers have given you three alternative systems: (a) a traditional temperature gauge that reads cold to the left, normal in the middle, and hot to the right; (b) a hot- engine warning light that flashes when the engine is about to overheat; and (c) a temperature gauge similar to (a), except that the entire gauge flashes on and off when the engine is about to overheat. You decide to test these three designs by having three separate groups of participants use the various warning systems in a driving simulator. The independent variable in this experiment is the type of warning system,…arrow_forwardResearchers want to test the effectiveness of a new anti-anxiety medication.
