In determining whether a new vaccine was better than the existing vaccine at preventing HPV. This is an example of (a) Clinical Trial.

Clinical trials are experiments or observations done for biomedical research studies on human participants to know about biomedical interventions, including new treatments (such as novel vaccines, drugs , medical devices) and known interventions that warrant further study and comparison. It also Help in establishing data on safety and efficacy.

Community-based clinical trials are type of clinical trials which are conducted directly doctors and clinics rather than at research centers. The trials give new medications for patients and also keep doctors involved with new developments in research.

Field trials are studies carried out "on the field", in people not admitted to any Hospital or Institution but they are done in the subject of the population, free from the disease These trials Help in Evaluating the new intervention to reduces the risk of developing a disease.

Time Trial refers to Fastest Development Of a medicine,drug or Vaccine. It is Race against the time Clock. It takes 7-10 years for a drug to be Approved and to pass all the Phases of Study to monitor it's Efficacy, Side-effects,Dosage etc.

Q1. Researchers were interested in determining whether there were any differences in the tendency to procrastinate based on birth order, i.e. first, second, or third child born. Using the data in the table below, answer the following questions. State the null and alternate hypotheses. What is the total sample size? Identify the independent and dependent variables What is the test statistic value? What is the p value? What is your conclusion (assume α = .05)? Phrase your conclusion based on...

Q4. Researchers were interested in determining whether gender and/or the number of tours soldiers served affected the incidence of PTSD. The PTSD impact instrument was used and scores were recorded upon discharge. State the null and alternate hypotheses. Include both interaction and main effect hypotheses (should be 3 null and 3 alternate hypotheses). What is the total sample size? Identify the independent and dependent variables List the test statistic and p value for the all your hypotheses? (Hint, there should...

Researchers were interested in determining a new drug for reducing high blood pressure. They obtained a sample of volunteers for the study and randomly divided them into two groups, C and T. A single medical practitioner, Dr. Daring, agreed to help the researchers in this study following a protocol of three steps: (i) The blood pressure of each subject was measured by Dr. Daring; (ii) the new drug was administered to subjects in group T and a placebo to subjects...

3.1. A researcher is interested in determining whether a new and cheaper method of analysis to determine the fat content of small organisms works as well as the older method used for many years. She has decided to split 15 samples and determine fat content in the two halves using the two methods. She has decided that simple linear regression will be the best method of analysis because she can test the hypothesis that the two methods give a 1:1...

Researchers from the university of Kent, UK, were interested in whether collectivist or individualist attitudes are related to one’s intent to comply with social distancing and safety guidelines during COVID-19. Participants were classified as either collectivist or individualist, and rated their intent to comply with guidelines on a scale from 1-5, where 1 is definitely not and 5 is definitely yes. Please conduct an independent-groups t test to determine if there is a significant difference in intention to comply between...
