- We've studied two different basic types of research studies, Observational Studies and Experiments. They have similarities and differences in their methodologies, and in some cases it is not practical nor ethical to design a study one way or the other. And this affects the kinds of conclusions the research can ultimately reach. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as the research conclusions to which they can possibly lead.A teacher was listening to some of her students talk about how many SnapChats they send during the day. The teacher decided that she wanted to conduct a study to see if the number of SnapChats a student sends per day affects how much time students talk to their friends face-to-face. So, the teacher let her 2nd period class continue sending Snaps as they always have. Then, the teacher told her 5th period that they were to not watch use SnapChat for a whole day. Then, the teacher had students record how many conversations they had with their friends during the week, gathered the data, and analyzed the results. What type of study is this? Experimental or observational?Describe the three ways identified in the text to find or develop a new research idea from existing research report(s).
- Formulate but do not solve the problem.In a survey of 1000 adults aged 18 and older, the following question was posed: "Are other travelers' online reviews trustworthy?" The participants were asked to answer "yes," "no," or "not sure." The survey revealed that 310 answered "no" or "not sure." It also showed that the number of those who answered "yes" exceeded the number of those who answered "no" by 470. What percentage of respondents answered "yes," "no," and "not sure"? (Let x represent the number of respondents who answered "yes", y represent the number of respondents who answered "no", and z represent the number of respondents who answered "not sure".) ___ = 1000 ___ = 310 ___ = 470COLUMBAN COLLEGE INC., OLONGAPO CITY SENIOR HIGH SCHOOL -BASIC EDUCATION DEPARTMENT ASINAN LEARNER'S MODULE Name of the Student Section: C No, it is unlikely reasonable that a 50 randomly selected SHS student would finish the examination in less than 43 minutes. STUDENT PLAYSHOP: WRITTEN WORKS General Directions: As a competent Columbanite, do the following activities for written works and performance tasks. Check Yourself! Solve the following problems. 1. The scores of individual students on a national test have a normal distribution with mean 18.6 and standard deviation 5.9. At Columban College, 76 students took the test. If the scores at this school have the same distribution as national scores, what are the mean and standard deviation of the sample mean for 76 students. (Assume that the population is infinite in each case). In 2015, the mean return of all common stocks on the Philippine Stock Exchange was 3-5%. 0 uns about 26%. A student of finance forms alWhat are the strengths and the weaknesses of experimental designs?
- I need to see if I am doing these problems correctly. I am more of a handwritten person so if you can show me how to write these out I would appreciate it for our teacher only shows us how to use a calculator. Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.9 hours to be admitted into the hospital. The standard deviation for these 15 patients was 1.4 hours. What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should…Plzz explain a) and b)Formulate but do not solve the problem.In a survey of 1000 adults aged 18 and older, the following question was posed: "Are other travelers' online reviews trustworthy?" The participants were asked to answer "yes," "no," or "not sure." The survey revealed that 350 answered "no" or "not sure." It also showed that the number of those who answered "yes" exceeded the number of those who answered "no" by 360. What percentage of respondents answered "yes," "no," and "not sure"?
