Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6
What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?
Psychologists Erik Erikson suggested that individuals go through eight developmental stages of life. Erikson believed that at stage 8 (age 65 to death), an adult's fear of death can be predicted by the
satisfaction they feel when reflecting back on their lives. To investigate, a psychiatrist interviewed a random sample of adults age 65 and older, and scored them on their satisfaction with their lives and
their fear of death. The psychiatrist wants to confirm Erikson's theory. What can be concluded with a =
0.01?

- A campus researcher wanted to investigate the factors that affect visitor travel time in a complex, multilevel building on campus. Specifically, he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building. Three subjects were assigned to each of the combinations of signs and starting locations, and travel time in seconds from beginning to destination was recorded. How should the data be analyzed?

For $2, a customer purchases three balls and attempts to roll each ball into a central target. The customer wins their $2 back and wins an additional $1 if they hit the target once, an additional $3 if they hit the target twice and an additional $5 if they hit the target three times. If the customer does not hit the target at all, they lose their initial $2. Access the data set labeled ”Skee-Ball” which reports the outcomes of 2,500 games for a single day’s operation of a Skee-Ball booth. (a) Define a random variable C (Customer Score) equal to the number of times a customer hits the target in each set of three rolls. How many possible outcomes of C are there? Report your answer as an integer. (b) Report the net profit ($) that the Skee-Ball booth achieved for the day. Report your answer as an integer. Hint: Estimate the PDF of C based on the relative frequencies: P(C = c) = Frequency of C = c / 2,500 (c) Report P(C = 0). Round your answer to three…arrow_forward
- Recent research commissioned by Vodafone suggests that older workers are the happiest employees (BBC News, July 21, 2008). The report documents that 70% of older workers in England feel fulfilled, compared with just 50% of younger workers. A demographer believes that an identical pattern does not exist in Asia. A survey of 120 older workers in Asia finds that 75 feel fulfilled. A similar survey finds that 58% of 210 younger workers feel fulfilled. (You may find it useful to reference the appropriate table: z table or t table) At the 5% level of significance, test if older workers in Asia feel less fulfilled than their British counterparts. a-1.

Four hundred men between the ages of 50 and 84 are recruited as participants. The men are divided randomly into two groups: one group will take aspirin, and the other group will take a placebo.

At the end of the study, researchers count the number of men in each group who have had heart attacks.

The Centers for Disease Control and Prevention (CDC) define a healthy sleep duration to be at least seven hours per day.

- An aircraft emergency locator transmitter (ELT) is a device designed to transmit a signal in the case of a crash. The Altigauge Manufacturing Company makes 80% of the ELTS, the Bryant Company makes 15% of them, and the Chartair Company makes the other 5%. The ELTS made by Altigauge have a 4% rate of defects, the Bryant ELTS have a 6% rate of defects, and the Chartair ELTS have a 9% rate of defects (which helps to explain why Chartair has the lowest market share). i) If an ELT is randomly selected from the general population of all ELTS, find the probability that it was made by the Altigauge Manufacturing Company.
