General health survey. The Centres for Disease Control and Prevention (CDCP) in Atlanta, Georgia, conducts an annual survey of the general health of the U.S. population as part of its Behavioural Risk Factor Surveillance System. Using random-digit-dialing, the CDCP telephones U.S. citizens over 18 years of age and asks them the following four questions:

1. Is your health generally excellent, very good, good, fair, or poor?

2. How many days during the previous 30 days was your physical health not good because of injury or illness?

3. How many days during the previous 30 days was your mental health not good because of stress, depression, or emotional problems?

4. How many days during the previous 30 days did your physical or mental health prevent you from performing your usual activities?

Identify the parameter of interest for each question

Short Answer

Expert verified

a. p = proportion with excellent health

b. μ= mean number of days when health is not good

c. μ= mean number of days when health is not good

d. μ= mean number of days when health is not good

Step by step solution

01

Given information

In the above survey being conducted, we have to find the parameters of interest in each question.

02

(a) General health

The parameter of interest is: p = proportion with excellent health. The term "health" refers to an entire condition of physical and mental well-being. Healthcare exists to assist individuals in maintaining their best health.

03

(b) Not good physical health 

The parameter of interest is: μ= mean number of days when health is not good. Healthy days are the polar opposite of unhealthy days. Healthy days are derived by subtracting the number of unwell days from 30 days as well as approximating the number of recent days when a patient's mental and physical well-being was excellent (or superior).

04

(c) Not a good mental health

The parameter of interest is: μ= mean number of days when mental health is not good because of stress, depression, or emotional problems. Unhealthy days estimate the total amount of time in the preceding 30 days when the participant's mental or physical well-being was not excellent. To get this estimation, integrate the results from questions 2 and 3 to create a summary score of overall unwell days, with a reasonable maximum of 30 problematic days.

05

(d) Prevents physical as well as mental health

The parameter of interest is: μ= mean number of days when physical or mental health is not good and prevents one from performing usual activities. Aerobic or a mixture of cardiovascular as well as muscular activities for 30 to 60 minutes three to five days a week have been shown to boost mental well-being. According to numerous studies, even low amounts of physical exercise may provide a few benefits. Regular physical exercise tends to lessen problems of stress or depression in adolescents as well as children. It is unsure if physical activity boosts self-esteem.

Radon exposure in Egyptian tombs. Refer to the Radiation Protection Dosimetry (December 2010) study of radon exposure in tombs carved from limestone in the Egyptian Valley of Kings, Exercise 6.30 (p. 349). The radon levels in the inner chambers of a sample of 12 tombs were determined, yielding the following summary statistics: x¯=3643Bq/m3and s=4487Bq/m3. Use this information to estimate, with 95% confidence, the true standard deviation of radon levels in tombs in the Valley of Kings. Interpret the resulting interval.

Minority ownership of franchises. According to a 2011 report for IFA Educational Foundation, 20.5% of all franchised businesses in the United States are minority owned. (This information is based on the U.S. Census Bureau’s survey of 27 million business owners.) Suppose that you obtain a sample of 100 franchised businesses located in Mississippi and find that 15 are owned by minorities. Does this result lead you to conclude that the percentage of minority-owned franchises in Mississippi is less than the national value of 20.5%? Explain.

The following sample of 16 measurements was selected from a population that is approximately normally distributed:

  1. Construct an 80% confidence interval for the population mean.
  2. Construct a 95% confidence interval for the population mean and compare the width of this interval with that of part a.
  3. Carefully interpret each of the confidence intervals and explain why the 80% confidence interval is narrower.

Aluminium cans contaminated by fire. A gigantic warehouselocated in Tampa, Florida, stores approximately 60million empty aluminium beer and soda cans. Recently, a fireoccurred at the warehouse. The smoke from the fire contaminatedmany of the cans with blackspot, rendering them unusable.

A University of South Florida statistician was hiredby the insurance company to estimate p,the true proportionof cans in the warehouse that were contaminated by the fire. How many aluminium cans should be randomly sampled toestimate pto within .02 with 90% confidence?

What is the confidence level of each of the following confidence intervals μ?

  1. χ¯±1.96σn
  2. χ¯±1.645σn
  3. χ¯±2,575σn
  4. χ¯±1.282σn
  5. χ¯±.99σn
