A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the agency, the uninsured rates in a recent year are as follows: 5.2% of those under the age of 18, 12.9% of those ages 18-64, and 1.3% of those 65 and older do not have health insurance. Suppose 22.4% of people in the county are under age 18, and 62.3% are ages 18-64. (a) What is the probability that a randomly selected person in this country is 65 or older? 15.3 (b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older?

Read the study below carefully. Then answer the questions that follow by typing in the letter of the correct response. Rhianna hears that watching ASMR videos on YouTube can help with insomnia. She conducts a sleep study on 60 people who have difficulty sleeping by asking a simple random sample of 30 participants to watch at least 20 minutes of ASMR videos prior to sleeping and the remaining 30 participants to attempt to sleep without watching any videos. During the study, the subjects are connected to an EEG machine, which is used to measure brain activity. Rhianna analyzes the EEG results and concludes that those who watched the ASMR videos experienced a better quality of sleep than those who did not. i. Identify the treatments in Rhianna’s study. A. being connected to an EEG machine B. experiencing difficulty sleeping C. watching at least 20 minutes of ASMR videos D. watching at least 20 minutes of non-ASMR videos E. watching no videos prior to sleep F. all…

The following table is from a publication. The individuals in the following table have an eye irritation, a nose irritation, or a throat irritation. They have only one of the three. Is there sufficient evidence to reject the hypothesis that the type of ear, nose, or throat irritation is independent of the age group at a level of significance equal to 0.05?

A warehouse manager wants to know if there is an association between the shift worked and being on time for work. To investigate, he selects a random sample of 70 workers and classifies each one according to the shift they worked most recently and whether they were on time for work. He was unable to classify a substantial number of people as being on time, so he classified those individuals as unknown. The data are displayed in the table. The manager would like to know if these data provide convincing evidence of an association between the shift worked and being on time in the large population of all workers at this warehouse. The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 5, so all expected counts are at least 5. Yes, the smallest expected count is 8.54, so all expected counts are at least 5. No, the smallest expected count is 2.56, so the expected counts are not all at least 5. No, the smallest expected count is…
An article reported that in a particular year, there were 717 bicyclists killed on public roadways in a particular country, and that the average age of the cyclists killed was 43 years. These figures were based on an analysis of the records of all traffic-related deaths of bicyclists on public roadways of that country. (a) Does the group of 717 bicycle fatalities represent a census or a sample of the bicycle fatalities for that year? O a census O a sample (b) If the population of interest is bicycle traffic fatalities for this particular year, is the given average age of 43 years a number that describes a sample or a number that describes the population? O a number that describes a sample O a number that describes the population
A 2012 study of freely forming groups in bars all over Europe examined the natural behavior of groups. The researchers recorded the group size (number of individuals in the group) of all 501 groups in the study that were naturally laughing.

A health educator wants to evaluate the effect of a dental film on the frequency with which children brush their teeth. Eight randomly chosen kids are measured on the number of times they brushed their teeth for one month before viewing the dental film and again for a month after the film.
