If I am to conduct research which involves a population of 2000 people, how many people would I need to have my questionnaire answered to consider my quanitative study valid?
Step by step
Solved in 2 steps
- You will conduct a study of 100 people with cancer to better understand people's view the role of nutrition in their cancer diagnosis and treatment. This mixed methods study will include quantitative data collection from all 100 persons and qualitative data collection from about 20 persons. Your aims to to describe: o Describe sources of information about cancer-related nutrition (who did they learn cancer- related information from?) o Assess knowledge about cancer-related nutrition o Understand nutrition-related behaviors people changed due to their cancer diagnosis or treatment State which aims would best be measured with quantitative data and which aims would best be measured with qualitative data. Explain why you would use quantitative or qualitative data collection for each.Your daughter is doing a case study with my husband to know which devices are used by the students in their online classes. As such, a survey was conducted to 100 engineering students at PUP. 54 of them use smartphone, 37 use laptop and 24 of the respondents use iPad. 21 of them use both smartphone and laptop. 13 of them use both iPad and smartphone. In addition to that, 18 of them use both iPad and laptop. Only 9 of the respondents use all the three devices in their online class. Those who do not have any devices are studying through modular approach. How many respondents are modular?You oversee assessing different training methods for effectiveness. You have data on 4 methods: Method 1 (?1 = 87, ?1= 12), Method 2 (?2= 92, ?2 = 14), Method 3 (?3= 88, ?3 = 15), and Method 4 (?4=75, ?4 = 11). Test for differences among these means, assuming ??B=64.81 and ??T=399.45.
- When looking at the data for graduate school admissions between men and women, it is shown that about 45% of men are admitted but only 38% of women. However, when the data is broken down by school it turns out that, within each school, the women are admitted at higher rates than the men. This could happen because I. The women apply in higher numbers to schools with lower acceptance rates. II. The women apply in higher numbers to schools with higher acceptance rates III. The men apply in higher numbers to schools with lower acceptance rates IV. The men apply in higher numbers to schools with higher acceptance ratesAlready did the questions that I understood but I need help with question b and question C. Thanks so much!Prof. Flores, always interested in improving her teaching effectiveness, has decided to undertake a careful analysis of her evaluations from the past three years. A matter of special concern to her is how she is viewed by students of different majors. She's decided to look at the last question on the teacher evaluation form, Question 17, which is, "Would you recommend this professor to another student?" Each of Prof. Flores' students can be placed into one of three categories according to the student's major school, as shown in the contingency table below. (Students who have majors from more than one school are not included.) This table contains a summary of the data that Prof. Flores has collected for 500 of her students. Each of the 500 students is classified according to two variables: major school ("School of Social Science", "School of Engineering", or "School of Physical Sciences") and response to Question 17 ("No", "Maybe", or "Yes"). In the cells of the table are written the…
- with my answer in screenshot 1 will you help me with the ones in screenshot 2 pleaseThe mechanics of a paired tt-test are very similar to a Student's tt-test.I think my numbers are right for the first two parts but can someone help me with part d please and just double check my numbers? Thank you in advance if you can!
- A research company is doing research on the number of Americans who have had COVID-19. They need to obtain a sample to estimate the population proportion of people who have had COVID-19. Based on a previous study at Stanford University, they believe the population proportion is approximately 13%. You would like to be 95% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?A doctor wanted to study the effect of four different treatments on mental health. A group of 100 adults experiencing depression volunteered for the study. The doctor randomly assigned one-fourth of them to each of four groups. Group 1 followed a specific exercise plan, group 2 followed a specific diet plan, group 3 followed an exercise and diet plan, and group 4 did not follow any plan. After 4 weeks, the doctor contacted each participant and asked them if they felt any better. The results are displayed in the table. The doctor would like to know if these data provide convincing evidence that the distribution of responses differs across the treatment groups in the population of all patients like these. The random condition is met. The 10% condition is not needed because random sampling did not take place. This table of expected counts shows that all expected counts are at least 5. What is the value of the chi-square test statistic? χ‑2 = 5.03 χ‑2 = 6.26 χ‑2 = 25.33 χ‑2 = 39.22
