SECTION 7D - ASSESSING THE RISKS1. A country has a population of 62 million.(a) Last year, there were 23,085 traffic fatalities. Find the fatality rate in deaths per 100,000population.(b) The leading causes of death are shown in the table below along with the actual number ofdeaths. The capital city is home to 2.5 million people. About how many people would youexpect to have died of stroke in the capital?CauseHeart disease CancerNumber ofDeaths147,00092,250AIDS52,890Stroke34,400PulmonaryDisease27,160 (c) The overall birth rate is 14.6 births per 1000. The overall death rate is 8.1 deaths per 1000.Based on births and deaths alone (not counting immigration), about how much does thepopulation of the country increase during this year?

Fatality rate is calculated to estimate number of people die due to particular disease. Population…

Difference in Two Proportions Problem. In a September 2019 survey of adults in the U.S., participants were asked if within the last 5 years, they knew of a friend or family member who died due to inability to pay for medical treatment. Overall, 13.4% answered yes. The rate for seniors (those 65 and over) is much lower at 6.6% due to Medicaide and Medicare. We will focus on the difference between the two younger age groups. The table below has the breakdown of the data by three Age Groups. Yes AGE 18-44 45-64 65+ Total 87 46 14 147 No 428 326 198 952 Total 515 372 212 1099 This problem will focus on a Difference of Proportion Problem between those 18 to 44 and those 45 to 64. Use this order, Proportion(18 to 44) - Proportion (45 to 64), in calculating the difference so it is positive. Answer the following questions. At first we will focus on the Confidence Interval for the Difference of Two Proportions. We will construct a 95% Confidence Interval of the difference in proportions. Do not…

An epidemiologist plans to conduct a survey to estimate the percentage of women who give birth. How many women must be surveyed in order to be 99% confident that the estimated percentage is in error by no more than two percentage points? Complete parts (a) through (c) below. Question content area bottom Part 1 a. Assume that nothing is known about the percentage to be estimated. n=enter your response here (Round up to the nearest integer.) Part 2 b. Assume that a prior study conducted by an organization showed that 81% of women give birth. n=enter your response here (Round up to the nearest integer.) Part 3 c. What is wrong with surveying randomly selected adult women? A. Randomly selecting adult women would result in an overestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have completed the time during which they can give birth. B. Randomly…
Please help me with this question.
researcher wonders if the amount of sleep new parents get is associated with how grumpy they are. The researcher recruits a sample of 100 new parents and asks them (1) how many hours of sleep they are getting each night, (2) how many hours of sleep their baby is getting each night, and (3) how grumpy they 4 are on a scale from 0 (not at all grumpy) to 100 (very grumpy). They saved the results to a file called hwo_parenthood. cs. Load the data into jamovi and answer the following questions. 3. What is the value of the test statistic for each association? 4. What is the degrees of freedom for each association? 5. What is the precise p-value as reported by jamovi for each association? Make sure you report the value to at least three decimal places. 6. Which of the associations are significant?? 7. What is the direction of each association ? 8. What is the effect size for each association? Are they weak, moderate, or strong? 9. What does each of the associations mean in plain language?
Chapter 5, Section 2, Exercise 051 More Information From the Online Dating Survey A survey conducted in July 2015 asked a random sample of American adults whether they had ever used online dating (either an online dating site or a dating app on their cell phone).College-Educated or Not?The survey also asked participants for their level of education, and we wish to estimate the difference in the proportion to use online dating between those with a college degree and those with a high school degree or less. The results are shown in the two-way table below. College High School Total Yes 157 70 227 No 666 565 1231 Total 823 635 1458Table 1: Have you ever used an online dating site or a dating app?
