Most major survey research organizations do not include wireless telephone numbers when conducting random-digit-dial telephone surveys. If there are differences between persons with and without landline phones, using a random-digit-dial telephone survey may introduce bias into the survey results Data on a broad range of health topics are collected through personal household Interviews of a representative sample of the U.S. civillan noninstitutionalized population in the National Health Interview Survey (NHIS). Since respondents are also asked about their telephones, the NHIS data allow you to compare the health status of persons with and without landline phones. Letp, denote the proportion of adults living in wireless phone-only homes who are diabetic and p, denote the proportion of adults living in landline phone homes who are diabetic. Independent random samples are selected from the two populations. Sample 1, with sample sizen - 310, provides a sample proportion , = 0.05. Sample 2, with sample size n = 600, provides a sample proportion P = 0.09. (The sample results are representative of the data collected in the NHIS, but the sample sizes are much smaller.) Use the Distributions tool to help you answer the questions that follow. Standard Normal Distribution Mr00 Sando 3 2 1 The 95% confidence interval estimate of p-p, is 0.038 AA 0.031 0.033 -0.0730 The 95% confidence interval estimate of p-p, is to Based on the 95% confidence interval estimate of you conclude that diabetes is prevalent among adults who live in Wireless phone-only homes compared with adults who live in landline phone homes. Thus, a random-digit dial health survey can be expected to the proportion of U.S. adults who have diabetes, 0.038 -11-0.007 0 ann 0.033 -0.04 The 95% confidence interval estimate of p, -p, is Based on the 95% confidence interval estimate of .- , you conclude that diabetes is prevalent among adults who live in wireless phone-only homes compared with adults who live in landline phone homes. Thus, a random.digit-dial health survey can be expected to the proportion of U.S. adults who have diabetes 2 aan equally more The 95% confidence interval estimate of p, -p, is to less Based on the 95% confidence interval estimate of p. - you conclude that diabetes is prevalent among adults who live in wireless phone-only homes compared with adults who live in landline phone homes. Thus, a random-digit-dial health survey can be expected to the proportion of U.S. adults who have diabetes aan 2 provide an unbiased estimate of te of p-p, is underestimate yal estimate of . - , you conclude that diabetes is prevalent among adults who live in wireless overestimate Jdults who live in landline phone homes.
